All That Glitters is not Gold

Appearance are often misleading. Many things may appear very attractive. When they are seen closely, they turn out to be disappointing. One cannot judge the quality of a thing by seeing its outside only. Every shinning metal is not gold.

Very often, things are not what they seem to be. We form our opinion about objects on the basic of superficial impression. One should always try to find out the true nature of things. We should try to find out the reality hidden behind their glittering exterior. A book with a beautiful cover has no guarantee of its being interesting..

The quality of anything can be judge only if we come to know the reality of a thing. Gold is gold if the inner metal is also gold. Many things are made of bad metals and to hide their defect, they need to be given a shine. They look beautiful and attract many people who love beautiful objects. An object with a glittering shin of gold cannot be gold unless the whole object itself is gold. All that glitters is not gold. All people wearing saffron clothes cannot be saints. A foolish man can never be wise by pretending to be wise.

Education and knowledge can improve awareness among the masses. A layman can be misled. But if he has knowledge about a particular thing, he cannot be cheated. One should use one's discretion to judge persons and things. One should not misled by external appearance.

Triangle

A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted .

By relative lengths of sides

Triangles can be classified according to the relative lengths of their sides:

In an equilateral triangle all sides have the same length. An equilateral triangle is also a regular polygon with all angles measuring 60°.[1]

In an isosceles triangle, two sides are equal in length.[note 1][2] An isosceles triangle also has two angles of the same measure; namely, the angles opposite to the two sides of the same length The 45–45–90 Right Triangle, is isosceles.

In a scalene triangle, all sides are unequal,[3] equivalently all angles are unequal. Right triangles are scalene if and only if not isosceles.

By internal angles

Triangles can also be classified according to their internal angles, measured here in degrees.

A right triangle (or right-angled triangle has one of its interior angles measuring 90° (a right angle). The side opposite to the right angle is the hypotenuse; it is the longest side of the right triangle. Triangles that do not have an angle that measures 90° are called oblique triangles.

A triangle that has all interior angles measuring less than 90° is an acute triangle or acute-angled triangle.

A triangle that has one angle that measures more than 90° is an obtuse triangle or obtuse-angled triangle.

A triangle that has two angles with the same measure also has two sides with the same length, and therefore it is an isosceles triangle. It follows that in a triangle where all angles have the same measure, all three sides have the same length, and such a triangle is therefore equilateral.

Triangle propertiesVertex The vertex (plural: vertices) is a corner of the triangle. Every triangle has three vertices.

Base The base of a triangle can be any one of the three sides, usually the one drawn at the bottom. You can pick any side you like to be the base. Commonly used as a reference side for calculating the area of the triangle. In an isosceles triangle, the base is usually taken to be the unequal side.

Altitude The altitude of a triangle is the perpendicular from the base to the opposite vertex. (The base may need to be extended). Since there are three possible bases, there are also three possible altitudes. The three altitudes intersect at a single point, called the orthocenter of the triangle. See Orthocenter of a Triangle.In the figure above, you can see one possible base and its corresponding altitude displayed.

Median The median of a triangle is a line from a vertex to the midpoint of the opposite side. The three medians intersect at a single point, called the centroid of the triangle. See Centroid of a Triangle

Area See area of the triangle and Heron's formula

Perimeter The distance around the triangle. The sum of its sides. See Perimeter of a Triangle

Interior angles

The three angles on the inside of the triangle at each vertex. See Interior angles of a triangle

Exterior angles

The angle between a side of a triangle and the extension of an adjacent side. See Exterior angles of a triangle

Also:

1. The shortest side is always opposite the smallest interior angle 2. The longest side is always opposite the largest interior angle

It is usual to name each vertex of a triangle with a single capital (upper-case) letter. The sides can be named with a single small (lower case) letter, and named after the opposite angle. So in the figure on the right, you can see that side b is opposite vertex B, side c is opposite vertex C and so on.

Alternatively, the side of a triangle can be thought of as a line segment joining two vertices. So then side b would be called

AC

. This is the form used on this site because it is consistent across all shapes, not just triangles.

Properties of all trianglesThese are some well known properties of all triangles. See the section below for a complete list

The interior angles of a triangle always add up to 180°

The exterior angles of a triangle always add up to 360°

Area

The area is half of the base times height.

"b" is the distance along the base "h" is the height (measured at right angles to the base)

Area = ½ × b × h

The formula works for all triangles.

Measures to Save our environment

Biodegradable plastic bags are better than the usual plastic bags. However, they are not ideal because of

energy levels needed to produce them. Try to lessen the amount of plastic grocery bags in your

environment. Reuse them when buying new groceries as often as only possible.

Deposit your empty plastic grocery bags and some fabric bags in a canvas tote hanging on your doorknob.

You will not forget them when you will leave the house. Do not litter plastic packaging in the landscape.

Dispose it properly in a trash. Do not buy storage containers. Use used packages for storage, like glass

containers and plastic boxes from yogurt, sour cream, cottage cheese, whipped cream etc. They are

fantastic storage utensils, and I use the plastic containers even in the freezer. Small glass containers are

also fantastic to store tiny tools, and higher glass containers are excellent for elongated utensils like pencils

and pens.

Let Us go green . We should reduce our plastic use.Do not buy objects in small plastic boxes; this is a

waste .Buy drinking water in reusable glass containers. You can also use filtered tap water in your

bottles. It is a less expensive alternative than bottled drinking water. Biodegradable plastic bags are

better than the usual plastic bags. However, they are not ideal because of energy levels needed to

produce them.

Think about eating less meat and consuming it only occasionally and consciously. The carbon dioxide

emission from the meat production is higher than the total emissions of all vehicles.

When you own a garden, use it for herbs and vegetable cultivation. It is healthy, satisfying, and

environmentally correct to grow your own food.Buy vegetables, preferably in their harvest season, and

use locally grown food. This would allow to avoid high-shipping costs and save on greenhouse energy

costs.Reuse egg-cartons for storage of small items.Decorate such used egg-cartons, other storage

boxes, or empty of their contents glass containers. You can paint or beautify them. I know that you have

an imagination and that you are creative. Use these gifts to make your life beautiful in yellowish-

greenish-blue colors with some spots of red.For your drawer-dividers use shoeboxes. Use old hanging

shoe organizers for storage of small items in your garage, basement or storage space.

Go organic ! Pesticides are not acceptable for you. An example, they cause even lower IQ in newborn

babies!Use compost, a natural fertilizer. If you do not have a garden, use community composts near you.

Having a compost pile in the garden is clean, odorless and free of pests. You can compost leftovers of

not cooked vegetables, fruit scraps, shredded leaves and weeds, grass clippings, eggshells, coffee

filters, tea bags, used kitchen towels and facial tissues. You cannot compost meat leftovers, dairy

products, and cooked-food leftovers.

Dry your clothes outside or indoor on a folding rack.Try not to use cosmetics based on petroleum.

Plant more trees , save water , reduce your carbon print .

Composition of Air

Air is the name given to the atmosphere used in breathing and photosynthesis. Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%. While air content and atmospheric pressure vary at different layers, air suitable for the survival of terrestrial plants and terrestrial animals is currently only known to be found in Earth's troposphere and artificial atmospheres.

Air is mainly composed of nitrogen, oxygen, and argon, which together constitute the major gases of the atmosphere. The remaining gases are often referred to as trace gases,[1] among which are the greenhouse gases such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Filtered air includes trace amounts of many other chemical compounds. Many natural substances may be present in tiny amounts in an unfiltered air sample, including dust, pollen and spores, sea spray, and volcanic ash. Various industrial pollutants also may be present, such as chlorine (elementary or in compounds), fluorine compounds, elemental mercury, and sulfur compounds such as sulfur dioxide [SO2].
