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.
Here’s a triangular pyramid printable free for you to use and cut out to answer those questions:
The following picture shows a triangular pyramid without faces which helps to emphasise how many edges it has.
Can you identify how many edges a triangular pyramid has from the following picture?
