The Vertex
It becomes an angle
the vertex
You are a vertex
A vertex.
They form a vertex because they are line segments. An angle is two rays with the same point
Will Any two rays form an angle?
Two intersecting rays form an angle. Without two rays you do not have an angle.
No. If the rays do not meet, there is no angle.
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.
the vertex of the angle
Two rays that share an endpoint form an angle.
the vertex is the point where two rays begin and form and angle
Perpendicular is the word I think you are looking for
