## What Is A Triangular Pyramid?

A triangular pyramid is an object made up of 4 triangle shapes.

It has a central triangle with the other three triangles connected to the central triangles edges, and each of those triangles connected together at one central point, like so:

To create your own triangular pyramid you can construct your own from a larger triangle as shown in the net below:

The labels on this net should help you to find out how many edges are on a triangular pyramid.

You’ll also notice there are other labels, such as
```
faces
```

and
```
corners
```

. When you’ve cut along the thick black line and folded the triangles up along the dotted line you should be able to see how many
```
faces
```

,
```
corners
```

and
```
edges
```

a triangular pyramid has.
