Are kp and pk the same ray? are nm and mn the same ray? explain your answer.

KP and PK cannot be the same ray and also NM and MN cannot be the same ray.

Explanation:

A Ray is said to be a single straight unidirectional infinity line. We can determine the starting point of a ray whereas we can't plot the endpoint of the ray.So PK and KP cannot be the same ray and there can't be the existence of such ray with the two points.In the same way, NM and MN can't be described as a ray because it doesn't satisfy the requirement of the ray.Hence the above coordinates cant be the same ray.
