Special Angle Pairs with Parallel Lines

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

What are alternate interior angles?

Back

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

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines on opposite sides of a transversal. They are equal in measure.

What are supplementary angles?

Back

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

Front

If one angle measures 75°, what is the measure of its supplementary angle?

Back

105° (because 180° - 75° = 105°).

Front

If ∠A and ∠B are alternate interior angles and ∠A = 65°, what is ∠B?

Back

∠B = 65° (because alternate interior angles are equal).

Front

What is the measure of angle A if it is a corresponding angle to angle B, and angle B measures 82°?

Back

∠A = 82° (because corresponding angles are equal).
