What are corresponding angles?

Back

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

What are alternate interior angles?

Back

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

What are consecutive interior angles?

Back

Consecutive interior angles are the pairs of angles that lie on the same side of the transversal and inside the two parallel lines. They are supplementary.

What are alternate exterior angles?

Back

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