Let A be an m n matrix. Then, AT is by de nition an n m matrix, and therefore TAT is n m as well. Since A = A , the dimensions of AT must be the same as the dimensions of A. Therefore, m n must be the same as n m, and so we can conclude that m = n. This means that A is n n, which means that A is a square matrix.
