Geometry: Sum of the angles in a triangle (a one-minute proof)

preview_player
Показать описание
We prove that the sum of the angles of any triangle is 180°. It is important to develop the skill of proving things, because when you understand *why* something works, it reinforces your knowledge.

A discussion of why the Parallel Postulate is equivalent to the corresponding (or alternate interior angles) of a transversal being equal would be very good to.

Proclus claimed that this proof originated from the Pythagoreans.
