Consider the square pyramid in Exercise 5.

**a)** How many vertices does it have?

**b)** How many edges (lateral edges plus base edges) does it have?

**c)** How many faces (lateral faces plus bases) does it have?

**d)** At which point are the lateral edges concurrent?

To determine

**(a)**

**To find:**

The number of vertices in the given figure.

Explanation

**Given:**

The figure given below

and base

**Properties Used:**

A pyramid is made by connecting a base to an apex or vertex. The base is flat with straight edges, no curves, hence, a polygon and all other faces are triangles. The altitude/height of the pyramid is the line segment from the vertex perpendicular to the plane of the base

To determine

**(b)**

**To find:**

The number of edges in the given figure.

To determine

**(c)**

**To find:**

The number of faces in the given figure.

To determine

**(d)**

**To find:**

Whether the given figure is a regular hexagonal pyramid.
