What Even Is A Pentagonal Trapezohedron

The nerdiest of geometry jokes has entered the chat! This meme captures that special brand of disappointment when you realize the d10 (ten-sided die) in Dungeons & Dragons isn't actually a Platonic solid. It's a pentagonal trapezohedron—basically the geometric equivalent of finding out your favorite band isn't technically indie.

For the uninitiated: Platonic solids are the geometric rock stars of 3D shapes—perfectly symmetrical polyhedra where all faces are identical regular polygons. There are exactly five (tetrahedron, cube, octahedron, dodecahedron, and icosahedron), and they're mathematical perfection. Meanwhile, the d10 is that weird cousin who didn't make the cut but still shows up to family reunions.

The crushing disappointment in the last panels is pure mathematical heartbreak. Geometry nerds and DnD players unite in shared trauma!
