Angles from Transversals

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.

Front

What are alternate interior angles?

Back

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

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie on the same side of the transversal and between the two parallel lines. They are supplementary, meaning their measures add up to 180 degrees.

What is the relationship between angles formed by a transversal and parallel lines?

Back

When a transversal intersects two parallel lines, several pairs of angles are formed, including corresponding angles, alternate interior angles, and consecutive interior angles, each with specific relationships.
