Well, it's been a long time since a lot of us took anything even slightly resembling a geometry class. You got a couple easy ones, but you definitely need to do some studying up if you wanna get the more difficult ones in this quiz!

## C+, Grappling with Geometry

Right!

While your memory about this stuff has faded a bit and caused you to forget some of the more obscure ones, overall you had a really impressive showing. Your memory has retained more about geometry than many would expect!

## B+, Geometry Great

Right!

You're a regular geometry genius! You took this quiz like you just learned this stuff yesterday - heck, we half-suspect that you might be a middle schooler or high schooler taking these classes right now!

## A+, Geometry Genius
