Parallel Lines and Transversals

Front

What is a transversal in geometry?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

How can you identify if two lines are parallel using angles?

Back

If a transversal intersects two lines and the corresponding angles are equal, then the lines are parallel.
