Understanding Triangular Pyramids

In this video, Mr. Jay explains the properties of a triangular pyramid, focusing on its faces, edges, and vertices. He begins by identifying and counting the four faces, followed by the six edges, and finally the four vertices. The video concludes with a summary of these properties, reinforcing the understanding of the geometric structure of a triangular pyramid.
