What are corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a straight line crosses two others.

If two lines are parallel, what can be said about the angles formed when a transversal crosses them?

Back

When a transversal crosses parallel lines, alternate interior angles are congruent, and corresponding angles are also congruent.

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

Back

The sum of the interior angles on the same side of the transversal is 180°.

Front

What is the definition of a transversal?

Back

A transversal is a line that crosses at least two other lines in the same plane.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines cross. They are always congruent.
