prove that the distance d(P,Q) between the points P(X1,X2,X3) and Q(X2,Y2,Z2) in space is (the distance formula for 3d points) by using point R(X2,Y2,Z2), the 2 dimensional distance formula within the plane z=z1, the one dimensional distance formula within the line r=<X2,Y2,t>, and the Pythagorean theorem.
