    The definition of polygon is a plane figure with at least three straight sides and angles

    and typically five or more. Polygons have been known since ancient times. The regular

    polygons were known to the ancient Greeks, and the pentagram, a non-convex regular

    polygon (star polygon), appears on the vase of Aristophonus, Caere, dated to the 7th century

    B.C. Non-convex polygons in general were not systematically studied until the 14th century

    by Thomas Bredwardine.

    In 1952, Shephard generalized the idea of polygons to the complex plane where each

    real dimension is accompanied by an imaginary one to create complex polygons. Surveyors

    use them in mapping land every day. Engineers use them for calculating force distribution.

    Painters use them for calculating the area of coverage they are going to be painting. They

    actually are used quite a bit in everyday life. Things like calculating the square footage of our

    home for insurance purposes, the square footage of a room for carpeting, the area of a yard

    for being sodded all will require the use of polygons. Any time we are calculating area we

    working with polygons.

    (ii) By comparing the length of p,q and the given side, determine the relation between


    p + q +100m = 300m

    p + q = 200m

    (iii) Triangle Inequality Theorem

    The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle

    must be greater than the the measure of the third side.

    Otherwise, you cannot create a triangle from the 3 sides.

    This rule must be satisfied for all 3 permutations of the sides. In other words, as soon

    as you know that the sum of 2 sides is less than the measure of a third side, then you

    know that the sides do not make up a triangle.


    c b



    In the figure, the following inequalities hold.

    a + b > c

    a + c > b

    b + c > a

    the herb garden to meet the demand are :

    Ginger Flower

    (Etlingera elatior)

  • 7/31/2019 Addmath Ateh New



    Etlingera elatior (also known as Torch Ginger, Ginger Flower) is a species of herbaceous

    perennial plant. Botanical synonyms includeNicolaia elatior, Phaeomeria magnifica,

    Nicolaia speciosa, Phaeomeria speciosa,Alpinia elatior,Alpinia magnifica.

    It is known in Malay as bunga kantan and it it eaten in a kind of salad preparation. The showy

    pink flowers are used in decorative arrangements while the flower buds are an important

    ingredient in dishes. Ginger flower is the soul of many Nyonya dishes such as the asam laksa,

    Nyonya fish stew and curry dishes such as perut ikan and gulai tumis. More importantly the ripe

    seed pods, which are packed with small black seeds, are an essential ingredient of the Karo

    version ofsayur asam, and are particularly suited to cooking fresh fish.

    Leaves ofE.elatiorhave the highest antioxidant, antibacterial and tyrosinase inhibition

    activities among fiveEtlingera species studied. Antioxidant properties (AOP) of leaves were

    significantly stronger than flowers and rhizomes. Leaves of highland populations had higher

    AOP values than lowland counterparts. Thermal drying of leaves led to drastic declines in

    AOP while freeze-dried leaves showed significant higher AOP values. Ethanolic extracts of

    inflorescences have antimicrobial activity and are cytotoxic to HeLa cells.Antioxidant

    activity of diarylheptanoids isolated from rhizomes is greater than -tocopherol.E.elatiorhas

    an antioxidant effect against lead-induced hepatotoxicity in rats.

    Vietnamese coriander

    (Persicaria odorata)

  • 7/31/2019 Addmath Ateh New



    Persicaria odorata, the Vietnamese coriander, is herbs which leaves are used in Southeast

    Asian cooking. Other English names for the herb are Vietnamese mint, Vietnamese cilantro,

    Cambodian mint and hot mint. In Malaysia and Singapore, it is called daun kesom or daun

    laksa(laksa leaf). The shredded leaf is an essential ingredient of laksa, a spicy soup, so

    much so that the Malay called it as daun laksa which means laksa leaf. It is not related to

    the mints, nor is it in the mint family Lamiaceae but the general appearance and odor are

    reminiscent. Persicaria odorata is in the family Polygonaceae, collectively known as

    smartweeds or pinkweeds.

    The Vietnamese coriander is a perennial plant that grows best in tropical and subtropical

    zones in warm and damp conditions. In advantageous conditions, it can grow up to 15 to

    30 cm. In the winter or when the temperature is too high, it can wither. The top of its leaf is

    dark green, with chestnut-colored spots while the leaf's bottom is burgundy red. The stem is

    jointed at each leaf.

    Ulam Raja

    (Cosmos caudatus)

  • 7/31/2019 Addmath Ateh New



    Ulam raja, literally meaning "the Kings salad", was brought by the Spaniards from Latin America,

    via the Philipphines to the rest of Southeast Asia. Ulam, a Malay word used to describe a preparation

    that combines food, medicine and beauty is the widely popular Malay herbal salad. As a Malaysian

    delight, it is served throughout the country from major hotels for tourists to buffet lunches or dinners

    for the locals. The Malay people believe that the herb is good for health and contains anti-aging

    properties or awet muda, and that it tones up blood circulation, strengthens the bones and promotes

    fresh breath. The Malay people believe that the herb is good for health and contains anti-aging

    properties or awet muda, and that it tones up blood circulation, strengthens the bones and

    Ulam Raja is an annual plant growing up 2 m in height. The leaves are soft and pungent

    while the stem is light green with a purplish hue and succulent. As night falls the leaves fold

    to close the terminal buds as the plant literally sleeps. The flowers can be found solitary or in

    a loose clusters and are produced on a single stalk on auxiliary heads.

    It contains 0.3 percent protein, 0.4 percent fat and carbohydrates, it is also rich in laksium and
