Montessori Geometry: Two Straight Lines Crossed by a Transversal

An introduction to two straight lines (not necessarily parallel) crossed by a transversal. Illustrates interior, exterior, alternate, consecutive, and corresponding angles.

In this presentation, the two straight lines crossed by a transversal are not necessarily parallel. It is an introduction to the terminology and aims to arrive at two conclusions:

Two straight lines cut by a transversal will form eight angles.

Two straight lines cut by a transversal form four interior and four exterior angles.
