2/17 - ANGLE RELATIONSHIPS VOCABULARY PRACTICE

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

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 alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal.

Front

What do supplementary angles add up to?

Back

Supplementary angles always add up to 180 degrees.

Front

What is the relationship between parallel lines and transversals?

Back

When a transversal crosses parallel lines, it creates several pairs of angles, including corresponding angles, alternate interior angles, and alternate exterior angles.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.

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 is the measure of a complete angle?

Back

A complete angle measures 360 degrees.

Front

If two angles are complementary, what is their sum?

Back

If two angles are complementary, their sum is 90 degrees.
