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
