### Angles In Life Presentation

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