    For Q to be orthogonal its inverse equals Q transpose. So for Q inverse to be orthogonal Q transposed must be orthogonal and based on the criteria for a matrix to be orthogonal i think this only occurs when all elements in the matrix are the same. course i only looked at the 2X2 case but i assume it would hold for all cases hope that made sense

    im not an expert on matrices so you might want a second opinion

    If something is Ortogonal, well then if u take the dot product of them, you will get=0
