10. Question 9 6 faces 8 vertices 12 edges
How many faces on the shape above?
How many vertices?
How many edges?
6 faces
8 vertices
12 edges

11. Question 10
What are the only 2D shapes that can be used to make platonic solids?
Regular Pentagon
Equilateral Triangle
Square
Platonic Solids have all faces made up by exactly the same regular polygon and all the faces are at the same angle to each other. There are only 5 platonic solids and they are shown above.

12. Question 11 Euler’s Rule F + V – E = 2 No Yes 10 edges
In the 1700’s a mathematician called Leonhard Euler found that when he added the number of faces and vertices in a polyhedron the total was always 2 more than the number of edges. His rule is often written as shown below:
Euler’s Rule F + V – E = 2
Is it possible to have a polyhedron with 8 faces, 8 vertices and 16 edges?
Is it possible to have a polyhedron with 10 faces, 12 vertices and 20 edges?
If a polyhedron has 6 faces and 6 vertices, how many edges does it have? No
Yes
10 edges
