Angle Pairs Practice

Front

What are vertical angles?

Back

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

Front

What is the definition of complementary angles?

Back

Complementary angles are a pair of angles whose measures add up to 90°.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are a pair of angles whose measures add up to 180°.

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

Which equation represents the relationship of angles that add up to 180°?

Back

x + 5x = 180.

Front

Which equation represents the relationship of angles that add up to 90°?

Back

x + y = 90.

Front

What is the equation to solve for x in the context of angle pairs?

Back

5x = 2x + 24.

Front

Are the angles ∠JNM and ∠LNK adjacent?

Back

No, they are not adjacent.

Front

What are the properties of vertical angles?

Back

Vertical angles are always equal in measure.

Front

What is the sum of the measures of complementary angles?

Back

The sum is always 90°.
