Question

which type of figure pyramid is?
plzz tell me​

Answer 1

A pyramid is a polyhedron for which the base is a polygon and all lateral faces are triangles. In this lesson, we'll only concern ourselves with pyramids whose lateral faces are congruent — that is, they're the same size and shape.

Technically, when the lateral faces are congruent triangles, the shape is known as a right pyramid, indicating that the apex — the vertex at which the lateral faces meet — is directly above the center of the base. In this lesson, when we use the term pyramid, we mean a right pyramid. But there are other types of pyramids, too.

A pyramid is typically described by the shape of its base. For instance, a triangular pyramid has a base that is a triangle, and a hexagonal pyramid has a base that is a hexagon.
