LEVEL 1 | Complementary, Supplementary, and Vertical Angles

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always 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 are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal. They are equal when the lines are parallel.

Front

If two angles are supplementary and one angle measures 72 degrees, what is the measure of the other angle?

Back

The other angle measures 108 degrees.

Front

If two angles are complementary and one angle measures 50 degrees, what is the measure of the other angle?

Back

The other angle measures 40 degrees.

Front

Find the measure of the missing angle if one angle is 92 degrees and they are supplementary.

Back

The missing angle measures 88 degrees.

Front

Find the measure of the missing angle if one angle is 43 degrees and they are complementary.

Back

The missing angle measures 47 degrees.

Front

What is the relationship between ∠1 and ∠3 if they are vertical angles?

Back

∠1 and ∠3 are equal in measure.
