A Survey of Right Angles in Convex Pentagons

A regular pentagon, of course, has no right angles, but irregular pentagons can have one, two, or three (but not four, nor five). There are two varieties for both two and three right angles in pentagons -- the right angles can be consecutive, or non-consecutive.
