| word | tetrahedron |
|---|---|
| definition | A solid shape formed by four flat faces. |
| eg_sentence | Her son's box kites was a tetrahedron, and its pyramid shape was easy to pick out among the traditional designs flown by the other children. |
| explanation | The simplest tetrahedron is made of four equal-sided triangles: one is used as the base, and the other three are fitted to it and each other to make a pyramid. But the great pyramids of Egypt aren't tetrahedrons: they instead have a square base and four triangular faces, and thus are five-sided rather than four-sided |
