    Euclidean geometry, pythagorean triples, a very involved explanation, takes a little patience to get. Your use of variables might be a source of confusion. Trying naming sides, a,b,c and numbers, length of sides, potentially odd m and n.

    You can give her the answer she wants, but right now you are trying to understand the theory.

    Once you understand it, you can always switch the variables back to the ones she likes.
