Use the law of cosines to prove that isometries preserve angles; that is suppose that T : R2 → R2 is an isometry and let P, Q, R E R2 be three noncollinear points in the plane. Denote the images of these points under the isometry by Q':=TQ, P':=T P, and R :=TR. Prove that, Use the law of cosines to prove that isometries preserve angles; that is suppose that T : R2 → R2 is an isometry and let...
