Back

The sum of all angles in a triangle is 180°.

Front

If angle A is 44°, what is the measure of angle B if angle A + angle B = 90°?

Back

Angle B = 46°.

Front

What is the definition of complementary angles?

Back

Two angles that add up to 90°.

Front

What is the definition of supplementary angles?

Back

Two angles that add up to 180°.

Front

If two angles are supplementary and one angle measures 132°, what is the measure of the other angle?

Back

48°.

Front

What is the relationship between parallel lines and corresponding angles?

Back

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

Front

If angle C is 90° and angle D is 45°, what is the measure of angle E if angle C + angle D + angle E = 180°?

Back

Angle E = 45°.

Front

What is the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are equal.
