Octagon
An octagon is a shape with 8 sides and 8 angles. It’s also a stop sign. It’s also the worst thing that ever happened to you during a test.
My math teacher drew an octagon and I thought it was a stop sign for my brain.
I saw an octagon and it looked like it was about to scream.
The octagon made me think I was in a geometry class, not a math test.
