Angles In Life PresentationBy Audrey Imbs
Angles in My Backyard
Vertical Angle
Vertical Angles:
Def: Are an 2 angles formed by lines that intersect. Vertical angles must share common point and be congruent. However, they aren’t adjacent.
Reasoning:
2 angles in
Lines the intersect to form vertical angles in
A shared common point
Are congruent
Bisected Angle
Bisected Angle:
Def.: A ray that divides an angle into two angles that are congruent.
Reasoning:
The angles in are divided by the ray in
Both angles are congruent because they are both about 45 degrees.
Supplementary Angles
Supplementary Angles;
Def.: Two angle measurements, with the sum of 180 degrees.
Reasoning:
Two Angles
The angle measurement for the middle bar is 180 degrees
Obtuse Angle
Obtuse angle:
Def.: A angle that has a measurement greater than 90 degrees, but less than 180.
Reasoning:
The angle in has a measurement greater than 90 degrees
The measurement is about 125 degrees
Complementary Angles
Complementary Angles:
Def.: Two angle measurements, with the sum of 90 degrees
Reasoning:
The angles in
is 50 degrees and the angle in is 40 degrees
The angles in is 90 degrees
Right Angle
A right angle:
Def.: A right angle is an angle that’s measurement is always 90 degrees.
Reasoning:
When measured, the angle in is exactly 90 degrees
The angle is neither acute of obtuse.
Acute Angle
Acute Angles:
Def.: An angle that has a measure less than 90 degrees.
Reasoning:
The angle in has a measure of 45 degrees
The angle is neither right nor obtuse
Straight Angle
Straight Angle:
Def.: An angle that is completely straight; therefore, it measures to 180 degrees.
Reasoning:
The angle in is completely straight and it s measure is 180 degrees.
Linear Pair
A Linear Pair:
Def.: A pair of adjacent angles whose non-shared sides are opposite rays. All vertical angles must be congruent.
Reasoning:
Angles in are adjacent
Therefore they share a common side in and a common vertex in
They are also have no common interior points and are on the same plane
Their non-common sides are opposite rays in
