Symmetry

You could take some photos of an example of symmetry at your place and send it to me.

We found out about rotational symmetry today.

16 letters have line symmetry: A, B, C, D, E, H, I, K, M, O, T, U, V, W, X, Y

6 letters have rotational symmetry: H, I, N, O, S, X, Z

4 letters have both: H, I, O, X

We discovered that a letter needs two or more lines of symmetry to have both types of symmetry.
