Show that Q is orthogonal iff WebMar 8, 2015 · If you want to have a more geometrical view of why this is the case, you can prove the following: If ‖ x ‖ = ‖ y ‖, then x + y and x − y bisects the angle between x and y. If ‖ x ‖ = ‖ y ‖ and the vector u bisects the angle between x and y, then the Householder reflector associated to u sends x into y (and vice versa0. haywood county court nc
