The pyramid is named according to the shape of the base. A cone is not a pyramid because it does not have triangular side faces. In this topic we will look at some examples of pyramids. Triangular-based pyramidA triangular-based pyramid is also known as a tetrahedron. It has four faces that are all triangles. This is the net of a regular tetrahedron. All sides are equilateral triangles. A triangular-based pyramid has 4 faces, 4 vertices including the apex and 6 edges. To build a triangular pyramid with construction materials, we would need 4 triangles that join at the edges to make a closed three-dimensional shape or 6 edge pieces and 4 corner pieces to make a frame. How many faces and vertices have a pyramid?All sides are equilateral triangles. A triangular-based pyramid has 4 faces, 4 vertices including the apex and 6 edges.
Can a pyramid have 3 faces?A triangular pyramid is a geometric solid with a triangular base, and all three lateral faces are also triangles with a common vertex.
