Vertical and Adjacent Angles Test

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

What are adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

If angle A and angle B are supplementary, and angle A measures 70 degrees, what is the measure of angle B?

Back

Angle B measures 110 degrees (180 - 70 = 110).

Front

Identify a pair of vertical angles in the figure: ∠1 and ∠4, ∠6 and ∠5, ∠2 and ∠4, ∠1 and ∠6.

Back

∠1 and ∠4 are vertical angles.

Front

What is the vertical angle to ∠h?

Back

The vertical angle to ∠h is ∠f.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of complementary angles is 90 degrees.

Front

Are angle ABC and angle CBD adjacent, vertical, or neither?

Back

Angle ABC and angle CBD are adjacent.

Front

Find the missing angle x if angle A is 160 degrees and angle B is x degrees, and they are supplementary.

Back

x = 20 degrees (160 + x = 180).

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal in measure.
