Question

prove that if C is an element of ray AB and C is not equal to A, then ray AB = ray AC using any of the following corollarys

3.2.18.) Let, A, B, and C be three points such that B lies on ray AC. Then A * B * C if and only if AB < AC.

3.2.19.) If A, B, and C are three distinct collinear points, then exactly one of them lies between the other two.

3.2.20.) Let A and B be two distinct points. If f is a coordinate function for L = line AB such that f(A)=0 and f(B)>0, then ray AB = {P is an element of L: f(P) is greater than or equal to 0}.

3.2.21.) Let A and B be two distinct points. The point M i s called a midpoint of line segment AB if M is between A and B and AM=MB.
