CPM UNIT 2 - 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 angles that are opposite each other when two lines intersect. They are always congruent (equal in measure).

Front

What do supplementary angles add up to?

Back

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

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal in measure.

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

How do you identify an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

If angle 4 is 50 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle would be 130 degrees, since 50 + 130 = 180.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of complementary angles is 90 degrees.

Front

What is the measure of vertical angles if one angle measures 120 degrees?

Back

The vertical angle will also measure 120 degrees.
