Transversals

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more other lines at distinct points.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position at each intersection where a transversal crosses two lines.

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

When two parallel lines are cut by a transversal, the corresponding angles are equal.

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that lie between the two lines and on opposite sides of the transversal.

What is the relationship between consecutive interior angles when two parallel lines are cut by a transversal?

Back

When two parallel lines are cut by a transversal, the consecutive interior angles are supplementary (add up to 180 degrees).
