Two rays with a common end point?

Answer 1

Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.

I assume the question is about a "common END point", and although you have not said so, what you want is to know what it is called. If that is the case, then the answer is an angle.

Answer 2

Angle
