Question from Madeline: How many vertices does a hexagonal pyramid have?? |
Hi Madeline,
A pyramid is
a geometric solid with one base that is a polygon and all other faces are triangles with a common vertex.
Pyramids are named by the shape of the polygonal base so the Great Pyramid of Giza is a square pyramid since the base is a square. The vertices are the vertices of the polygonal base plus the one more vertex at the peak. Thus the Great Pyramid of Giza has 5 vertices.
