The solution for the first problem is: G,O,Q,S - All these are
letters with curves. Just like the letters given: D,P,R,J,C,U. None
of the letters are completely straight.

Well done! Joanna from Seal Primary School
looked at the second set of letters and said:

Well, my solution is K, N, M, V, A, W, X, Y and Z. I've picked
these letters because they all have acute angles and all have
straight line segments only.

Christina suggest two sets of her own:

1. B,D,P,Q - They all have only one straight line.

2. A,K,Q,R,S,V,W,M,N,X,Y,Z - They all have diagonal
lines.
