A regular polyhedron has equal size faces as in the case of a tetrahedron which is a triangular base pyramid that has 4 equilateral triangle faces.
A triangular pyramid has a triangular base and three triangular faces meeting at its apex. A square pyramid has a square base and four triangular faces meeting at its apex.
There would be 8 faces. Each square pyramid has 1 square face (its base) and 4 triangular faces. When you glue the squares together, you get a new polyhedron with 8 faces.
A square pyramid has a square base and four congruent triangular faces.
1. triangular prism it has 2 triangular faces. 2.triangular base pyramid, it has 5 triangular faces. 3. square base pyramid, it has 4 triangular faces.
A three sided pyramid.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
It's an Octohedron, which has 8 triangular faces. Think of one of the great pyramids in Egypt, with a square base and four triangular sides. Take two of these, turn one upside down, and glue them together along the square base. You wind up with 8 triangular faces, and 12 edges!
A triangular dipyramid - two triangular pyramids stuck together, base-to-base.
A regular polyhedron has equal size faces as in the case of a tetrahedron which is a triangular base pyramid that has 4 equilateral triangle faces.
Tetrahedron - a pyramid with a triangular base.
This is a "trigonal pyramid" or "tetrahedron."
A polyhedron can have any number of faces 4 or higher.
A triangular pyramid has a triangular base and three triangular faces meeting at its apex. A square pyramid has a square base and four triangular faces meeting at its apex.
A square based pyramid.
A tetrahedron is a geometric solid with four triangular faces, six edges, and four vertices. It is a type of polyhedron with triangular faces meeting at each vertex.
There would be 8 faces. Each square pyramid has 1 square face (its base) and 4 triangular faces. When you glue the squares together, you get a new polyhedron with 8 faces.
