SOL 8.5 Review: Angles

Front

What are adjacent angles?

Back

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

Front

What are vertical angles?

Back

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

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

What is the measure of an angle that is supplementary to a 40º angle?

Back

The angle that is supplementary to a 40º angle measures 140º.

Front

What is the measure of an angle that is supplementary to a 130º angle?

Back

The angle that is supplementary to a 130º angle measures 50º.

Front

What is the relationship between two angles that add up to 180 degrees?

Back

They are called supplementary angles.

Front

What is the relationship between two angles that add up to 90 degrees?

Back

They are called complementary angles.

Front

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

Back

Vertical angles are congruent, meaning they have equal measures.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on different parallel lines cut by a transversal.
