What language did hedron come from?

The word "hedron" comes from the Greek word "hedra", meaning "seat" or "base".

This is because in geometry, a hedron is a polyhedron, which is a three-dimensional figure with flat faces. The faces are often described as being the "seats" or "bases" of the solid.

So, the next time you see a cube, think of its faces as little "hedras"!
