I believe this is called the APEX.
An angle is formed by two rays with a common endpoint.
It's true, an angle is made up of two rays. Two rays meet at a point, and their relative position at the point where they meet will define an angle.
No. If the rays do not meet, there is no angle.
the vertex of the angle
When two rays meet at a common endpoint, an angle is formed.
