COMPLEMENTARY

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

SUPPLEMENTARY

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

Multiple Choice

True or False. These angles are complementary.

• True

• False

Finding x.

To determine the complement, subtract the given angle from 90.

90 - 68 = 22

x = 22

Multiple Choice

True or False.

These angles are supplementary.

• True

• False

Finding missing angle.

To determine the supplement, subtract the given angle from 180.

180 - 135 = 45

Missing Angle = 45
