Which is a property of an angle? O has two sides that each extend forever in both directions
O has two endpojints
O has two center points
O has two rays that share a common endpoint

has two rays that share a common endpoint

Step-by-step explanation:

An angle is formed by a two rays that share a common endpoint.  The distance between the two rays is what makes the measure of the angle wider or smaller.  Each ray extends in one direction forever; however since they share an endpoint, the rays do not extend in both directions forever.  There is only one endpoint, not two, and there is only one center point (vertex), not two.

I hope this helps you :)

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
