Angle Relationship Practice

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 vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are linear pairs of angles?

Back

Linear pairs are two adjacent angles that form a straight line. Their measures add up to 180 degrees.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles on opposite sides of a transversal but inside the two lines. 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.

How do you find the measure of a missing angle in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees. Use this to find the missing angle.

What is the equation for finding a missing angle if one angle is known?

Front

If two angles are supplementary and one angle measures 70 degrees, what is the measure of the other angle?
