They can have only one point in common.
It is the opposite ray.
One. Because a ray starts with a fixed point and endlessly extends on the opposite side. Thus there is only one endpoint.
An opposite ray is a pair of rays that share the same endpoint and extend in opposite directions. This can be visualized as two rays emanating from a common point but extending in opposite directions along the same line.
In ordinary geometry, no. Any ray will have infinitely many points.
A ray has many points but only on e endpoint
Opposite Ray!
A ray has 1 endpoint.
Two angles with two common points is commonly called a ray. An adjacent angle is an angle that has one common side and a common vertex.
1.
It has one endpoint.
