Angle Relationships Practice

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 supplementary angles?

Back

Supplementary angles are two angles that add up to 180°.

Front

What are complementary angles?

Back

Complementary angles are two angles that add up to 90°.

Front

If m∠1 = 30°, what is m∠2 if m∠1 and m∠2 are supplementary?

Back

m∠2 = 150°.

Front

If m∠3 = 60°, what is m∠4 if m∠3 and m∠4 are vertical angles?

Back

m∠4 = 60°.

Front

What is the relationship between adjacent angles?

Back

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

Front

If two angles are complementary and one angle measures 40°, what is the measure of the other angle?

Back

The other angle measures 50°.

Front

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

Back

The sum is 180°.

Front

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

Back

Their measures are equal.

Front

What is the relationship between angles that form a linear pair?

Back

Angles that form a linear pair are supplementary.
