Vertical and Adjacent Angles Test

Front

What are vertical angles?

Back

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

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

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

If m∠1 = 30°, what is m∠3 if they are vertical angles?

Back

m∠3 = 30°.

Front

If two angles are supplementary and one angle measures 70°, what is the measure of the other angle?

Back

The other angle measures 110°.

Front

What is the relationship between adjacent angles?

Back

Adjacent angles share a common side and vertex, and they can be complementary or supplementary.

Front

If m∠2 = 150°, what is the measure of the angle that is vertical to it?

Back

The vertical angle to m∠2 is also 150°.

Front

What is the value of y if m∠1 + m∠2 = 180° and m∠1 = 99°?

Back

y = 81°.

Front

Find the missing angle x if m∠A + m∠B + x = 180° and m∠A = 60°, m∠B = 90°.

Back

x = 30°.
