With these four cuts—from B to E, D to G, F to A, and H to C—we’ve got four triangles and a square in the middle.

I challenge you to say the alphabet backwards -- Z, Y, X, W, V, U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, C, G, A. Like that.

Try saying the alphabet backwards as fast as you can. Z, Y, X, W, V, U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, C, B, A, like that.
