Parallel Lines and AnglesStreaming Video - 2008
Euclid may not have invented parallel lines, but he was probably the first to recognize their implications. This program wraps up the topic of angles by introducing the Parallel Postulate and the Corresponding Angle Postulate, along with three theorems for dealing with alternate interior, alternate exterior, and same-side interior angles. Three proofs are also included.
