tetrahedron
No, the pyramids of Egypt are not equilateral triangles. They are three-dimensional structures with a square base and four triangular faces that converge at a point at the top. The triangular faces are typically isosceles triangles rather than equilateral triangles. The angles and proportions of the pyramids vary, but their design is not based on equilateral triangles.
A pyramid - it has a square base, and four triangles meeting to a point at the top.
The shape you are describing is a triangular prism. It has an odd number of vertices (5), four of its faces are isosceles (two triangular and three rectangular faces), and it has an even number of edges (9). This configuration meets all the specified criteria.
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.
Here is one way: /\ --- /\/\ ----- These are {45°, 45°, 90°} triangles. There are 3 on the bottom row, and 1 on top. Actually, any four identical isosceles triangles would work.
Isosceles TetrahedronA solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.
The tetrahedron. If one of the four triangles is equilateral and all others are isosceles, then one might also call it a (triangular-based) pyramid.
A three-dimensional figure or shape, such as a tetrahedron, has four faces. These faces are equilateral triangles. A tetrahedron also has four vertices and 6 edges.
A triangular pyramid has.

Oh, dude, you're talking about a triangular pyramid! It's like a pyramid, but with a twist - literally, because it's got those isosceles triangles for faces. And hey, it's got an even number of edges to keep things interesting. So yeah, that's your shape right there.

A pyramid has a variable number of triangular faces. The base of a triangle can be practically any regular shape, starting with a triangle. Technically a pyramid can have four or more triangles as faces.
