MODERATORS
They could have used terms like “convex” and “concave” to describe the shapes, but then again, I’m really picky when it comes to math.
The convex ones are concave on the other side. The straight piece is generally called "the straight piece"
The ones on the right contain some exterior angles that are less than 180 degrees, giving them concavity. Not every exterior angle of these shapes is this way, but due to having some exterior angles like this, I called them concave. The ones on the left have none of these such angles.
I agree with calling a straight a straight.
