Polydron

We've been creating 3D shapes with Polydron.

We have tested Euler's formula of
Faces + Vertices - Edges = 2
and found it worked!

The formula is written as: F+V-E = 2

We then made some polyhedrons of our own. These are 3D shapes that have only straight edges and flat faces.

We then checked that Euler's formula worked for our shapes. You'll be pleased to hear it did!
