A six-sided shape is called a hexagon.

Quick Scoop: What Is a Six Sided Shape Called?

When you’re talking about a flat, closed shape with six straight sides, the standard mathematical name is hexagon.

  • Any 2D six-sided polygon → hexagon.
  • If all six sides and all six angles are equal → regular hexagon.
  • If the sides or angles are not all equal → irregular hexagon.

A nice way to remember it:

“Hex” comes from the Greek word for six , and “gon” comes from the Greek for angle.

So if someone asks “what is a six sided shape called,” the simple, complete answer is: hexagon.

Tiny Extra: 3D Version

If you ever hear about a three-dimensional shape with six faces, that’s called a hexahedron , not a hexagon. But for normal school geometry questions about a six-sided shape on paper, the correct word is hexagon.

TL;DR: A six-sided shape is called a hexagon.
