7.G.5

Front

What is a supplementary angle?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If one angle measures 70 degrees, what is the measure of its supplementary angle?

Back

110 degrees.

Front

What is the measure of a right angle?

Back

90 degrees.

Front

If two angles are adjacent and form a right angle, what is the relationship between their measures?

Back

The sum of their measures is 90 degrees.

Front

What is the measure of the missing angle if one angle measures 30 degrees and they form a right angle?

Back

60 degrees.

Front

If angle ABD measures 100 degrees, what is the measure of angle DBC if they are supplementary?

Back

80 degrees.

Front

What is the formula to find the measure of a missing angle when two angles are supplementary?

Back

Measure of missing angle = 180 degrees - measure of known angle.

Front

If one angle measures x degrees and the other measures 30 degrees, what is the equation to find x if they form a right angle?

Back

x + 30 = 90.

Front

What is the measure of the missing angle if the options are 60, 70, 50, and 140 and the correct answer is 50?

Back

The missing angle is 50 degrees.

Front

What is the sum of the measures of two angles that are complementary?

Back

The sum is 90 degrees.
