Front

What is the definition of parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is the Triangle Angle Bisector Theorem?

Back

An angle bisector in a triangle divides the opposite side into segments that are proportional to the other two sides.

Front

What is the definition of a transversal?

Back

A line that intersects two or more lines at different points.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.
