Complementary Angles

COMPLEMENTARY

two angles are complimentary when adding their measure of degree together equals 90.

Complementary Angles

angles that add to 90^o

Complementary Angles

• These can be adjacent (touching or share a side)

• These can be non-adjacent (not touching or do not share a side)

Multiple Choice

• C

• D

Complementary Example 1

Open Ended

Solve for x.

Supplementary Angles

SUPPLEMENTARY

two angles are supplementary angles when adding their measure of degree equals 180.

Supplementary Angles

angles that add to 180^o

Supplementary Angles

• These can be adjacent (touching or share a side)

• These can be non-adjacent (not touching or do not share a side)
