Understanding a Pentagonal Pyramid

In this video, Mr. J explains how to determine the number of faces, edges, and vertices of a pentagonal pyramid. He begins by counting the six faces, then moves on to identify the ten edges, and finally counts the six vertices. The video provides a clear and structured approach to understanding the geometric properties of a pentagonal pyramid.
