i have read in a book that characteristic of an orthogonal matriks is (A'.A) = I, with A is an matrix, A' is transpose of A and I is an Identity matrix, the characteristic shows that A must be an orthonormal matriks,and my question is, can we say that every orthogonal matrix must be an orthonormal matrix?
