Front

What are Supplementary Angles?

Back

A pair of angles that add up to 180 degrees.

Front

What is the equation to find a missing angle if one angle is 64 degrees?

Back

x + 64 = 180

Front

What type of angles are formed when two angles add up to 180 degrees?

Back

Supplementary Angles.

Front

If one angle measures 100 degrees, what is the measure of its supplementary angle?

Back

80 degrees.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect, and they are always congruent (equal in measure).

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are always congruent (equal measures).
