Question 8 A B C D E F Side D Side C When the net above is folded to make a cube: What side is opposite the A? What side is opposite the E? Side D Side C

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

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.

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
