Presentation on theme: "Any two angles whose sum is 180 degrees. Supplementary Angles."— Presentation transcript:


1

*

2 any kind of two angles whose amount is 180 degrees. Supplementary angle

*

3 70+x=180 x=110 Example:

*

4 complementary Angles any kind of two angle whose amount is 90 degrees.

*

5 Example: x+(x+30)=90 2x+30=90 2x=60 x=30

*

6 2 angles across from each other on intersecting lines. Lock are constantly congruent! Vertical angles

*

7 Examples: b= ____ degrees

*

8 nearby Angles two angles that are alongside each other and also share a typical side.

*

9 Example: usual side

*

10 straight Pair 2 angles that are surrounding and supplementary. They form a directly line!

*

11 Example: 9x+3x=180 12x=180 X=15
