8.G.5. Review Flashcard

Front

What is the measure of angle 1 if angle 2 is 55 degrees and they are complementary?

Back

Angle 1 = 35 degrees (Complementary angles sum to 90 degrees).

Front

If angle A is 90 degrees, what type of angle is angle A?

Back

Angle A is a right angle.

Front

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

Back

The sum of the interior angles of a triangle is 180 degrees.

Front

If angle 1 is 135 degrees, what is the measure of its supplementary angle?

Back

Supplementary angle = 45 degrees (Supplementary angles sum to 180 degrees).

Front

What is the measure of angle C if angle A is 64 degrees and angle B is 116 degrees in a triangle?

Back

Angle C = 0 degrees (This is not possible in a triangle).

Front

What do you call an angle that measures more than 90 degrees but less than 180 degrees?

Back

An obtuse angle.

Front

If two angles are vertical angles, what can you say about their measures?

Back

Vertical angles are equal in measure.

Front

What is the measure of angle 3 if angle 1 is 135 degrees and they are vertical angles?

Back

Angle 3 = 135 degrees.

Front

If angle A is 26 degrees, what is the measure of angle B if they are complementary?

Back

Angle B = 64 degrees.

Front

What is the measure of angle 2 if angle 1 is 102 degrees and they are supplementary?

Back

Angle 2 = 78 degrees.
