Well i need to show or tell that any two rays can be congruent if ___


Anyways. Here are some ways that i thought they can be congruent:
Since a ray looks like this

.------> ray 1
.------> ray 2

Lets say the point on ray 1 is a and the point on ray 2 is b

So for a ray to be congruent their starting point must start in the same place since the other half which is a line runs infinitely so a and b must have the same distance. Is there another way, for some reason i'm just not seeing it.
