Diagrams, week 2

We are classifying hexagons in the geometry course for future elementary and special ed teachers. There aren’t many established types of hexagons, so we made a few up.

Stacy is a hexagon with exactly three congruent acute angles. A Bob is a hexagon with exactly 5 right angles. We are pretty sure—but have not formalized the argument—that it is impossible for a Stacy to also be a Bob.
