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

Define Corresponding Angles.

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal in measure.

Front

What are Supplementary Angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

Define Complementary Angles.

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is a Transversal?

Back

A transversal is a line that passes through two or more lines in the same plane at different points.

Front

What is the relationship between Angle 2 and Angle 6 if they are Corresponding Angles?

Back

If Angle 2 and Angle 6 are corresponding angles, they are equal in measure.

Front

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

Back

The sum of the measures of two supplementary angles is 180 degrees.

Front

If Angle 5 measures 32 degrees, what is the measure of its Supplementary Angle?

Back

The measure of the supplementary angle is 148 degrees (180 - 32 = 148).

Front

What is the relationship between Alternate Interior Angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

If Angle 1 is 70 degrees, what is the measure of its Complementary Angle?

Back

The measure of the complementary angle is 20 degrees (90 - 70 = 20).
