Final Math 1B Topic 7-3

Front

What is the measure of an angle that is complementary to a 45-degree angle?

Back

45 degrees (since complementary angles sum to 90 degrees).

Front

What is the sum of the interior angles of a triangle?

Back

180 degrees.

Front

If two angles are supplementary, what is the relationship between their measures?

Back

Their measures sum to 180 degrees.

Front

What is the measure of an angle that is supplementary to a 95-degree angle?

Back

85 degrees (since supplementary angles sum to 180 degrees).

Front

What is the definition of a right angle?

Back

An angle that measures exactly 90 degrees.

Front

What is the measure of an angle that is vertical to a 66-degree angle?

Back

66 degrees (vertical angles are equal).

Front

If one angle measures 50 degrees, what is the measure of its complement?

Back

40 degrees (90 - 50 = 40).

Front

What is the definition of an acute angle?

Back

An angle that measures less than 90 degrees.

Front

What is the measure of an angle that is complementary to a 29-degree angle?

Back

61 degrees (90 - 29 = 61).

Front

What is the definition of a straight angle?

Back

An angle that measures exactly 180 degrees.
