vertex
A line
that one!
an angle
Opposite rays are rays that share the same endpoint (have a common endpoint), but they also form a line.Not always.
Start in the same point but are going in opposite directions
An Angle

When two rays are joined at their endpoints, the resulting figure is called an angle. The point where the rays meet is known as the vertex, while the rays themselves are referred to as the sides of the angle. Angles can be measured in degrees to indicate their size.
Two and only two rays having the same end points are in an angle.
A line segment has two endpoints. Lines are infinite, so they have no endpoints; while rays start at one point and continue infinitely; and line segments are completely finite, so they have endpoints at both ends.
An angle.
no it has one endpoint and one arrow stating that it will go on forever
