Complementary and Supplementary Angles

Front

Complementary angles are angles that together equal

Back

90 degrees.

Front

Find the missing angle if one angle is 35 degrees.

Back

55 degrees (because 90 - 35 = 55).

Front

Find the missing angle if one angle is 25 degrees.

Back

65 degrees (because 90 - 25 = 65).

Front

Find the missing angle if one angle is 40 degrees.

Back

50 degrees (because 90 - 40 = 50).

Front

Find the missing angle if one angle is 10 degrees.

Back

80 degrees (because 90 - 10 = 80).

Front

Supplementary angles are angles that together equal

Back

180 degrees.

Front

Find the missing angle if one angle is 120 degrees.

Back

60 degrees (because 180 - 120 = 60).

Front

Find the missing angle if one angle is 90 degrees.

Back

90 degrees (because 180 - 90 = 90).

Front

Find the missing angle if one angle is 150 degrees.

Back

30 degrees (because 180 - 150 = 30).

Front

Find the missing angle if one angle is 80 degrees.

Back

100 degrees (because 180 - 80 = 100).
