Characteristics of a Regular Tetrahedral Pyramid

A regular tetrahedral pyramid is a three-dimensional geometric shape. It has the following characteristics:

Vertices (Points): 5 vertices total. There is 1 vertex at the tip of the pyramid and 4 vertices that make up the base tetrahedron.

Edges: 8 edges total. The 4 edges of the base tetrahedron plus 4 more edges connecting the vertices of the base to the vertex at the tip.

Faces: 5 faces total. There is 1 square face forming the base and 4 triangular faces that connect the base to the tip vertex.

The key properties that define a regular tetrahedral pyramid are having 5 vertices, 8 edges, and 5 faces. I hope this information helps explain the characteristics being asked about! Let me know if you need any clarification or have additional questions.
