Angles and Triangles

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 is the sum of supplementary angles?

Back

The sum of supplementary angles is 180 degrees.

Front

If angle A is 30 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle is 150 degrees.

Front

What is the relationship between same-side interior angles?

Back

Same-side interior angles are supplementary, meaning they add up to 180 degrees.

Front

If angle P measures 60 degrees, what is the measure of angle Q if they are complementary?

Back

Angle Q measures 30 degrees.

Front

What is the measure of angle x if angle y is 90 degrees and they are complementary?

Back

Angle x measures 90 degrees.

Front

Define complementary angles.

Back

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

Front

If angle 5 measures 63 degrees, what is the measure of angle 3 if they are same-side interior angles?

Back

Angle 3 measures 117 degrees.

Front

What is the measure of angle x if it is vertical to angle 8 which measures 70 degrees?

Back

Angle x also measures 70 degrees.

Front

What is the measure of angle C if angle P measures 60 degrees and they are supplementary?

Back

Angle C measures 120 degrees.
