prove that if C is a point on ray AB and c is not equal to A

prove that if C is a point on ray AB and c is not equal to A then AB equals AC. I need a proof PLEASE,

Solution

*Given that AB is a ray , one of the end should be fixed and other end can be extended

Aslo given that C is point on ray AB

*As given that C not equal to A , which implies that the A should be an end point .

*in ray AB ,A is end point and B is some other point on ray AB,Similarly C is some point on ray AB

* As both AB and AC are rays and both have end point as A ,Imples that AB equals AC
