Find Unknown Angle

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

Find the missing angle if one angle is 48 degrees and they are supplementary.

Back

The missing angle is 132 degrees (180 - 48 = 132).

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If angle 1 is 62 degrees, what is the measure of angle 2 if they are complementary?

Back

Angle 2 is 28 degrees (90 - 62 = 28).

Front

Identify the relationship: If angle A and angle B are supplementary, what can you say about their measures?

Back

The measures of angle A and angle B add up to 180 degrees.

Front

If angle 8 is 40 degrees, what is the measure of its vertical angle?

Back

The vertical angle is also 40 degrees.

Front

Find the missing angle if angle 3 is 72 degrees and they are complementary.

Back

The missing angle is 18 degrees (90 - 72 = 18).

Front

What is the sum of the measures of two supplementary angles?

Back

The sum is always 180 degrees.

Front

If angle 5 is 90 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle is 90 degrees (180 - 90 = 90).
