You can rotate a rectangle through 90 degrees using 2 reflections, but the mirror line for one of them should be diagonal. A reflection is the flipping of a point or figure over a line of reflection (the mirror line). Any translation can be replaced by two rotations. If we apply two rotations, we need U(R 2R 1) = U(R 2)U(R 1) : (5) To make this work, we need U(1) = 1 ; U(R 1) = U(R . Any rotation that can be replaced by a reflection is found to be true because.
