This video is a high quality training video from The Guerrilla CG Project a non for profit organisation dedicated to teaching the fundamentals of computer graphics.
The polygon is the basic building block of all 3d models. Here we discover its properties, like the face normal, which shows the direction the polygon is facing and it's three components the face, edge and vertex. Complicated objects are made of lots of polygons put together.
*Edit, the terms "Planar" and "Non Planar" should be "Coplanar" and "Non Coplanar" respectively.
