Answer (2)
In geometry, a ray is a part of a line that starts at a point and extends infinitely in one direction. It is named with two points: the endpoint and another point that is in the direction in which the ray extends. The notation for a ray is denoted with an arrow above the two points, pointing in the direction of extension.
In the given problem, you have the ray denoted as \overrightarrow{QP}. This means the ray starts at point Q and extends through and beyond point P.
However, the symbol representation provided is P | Q -->, which visually suggests that Q is the starting point and the ray is extending towards the right through point P. Therefore, naming the ray \overrightarrow{QP} is actually not correct if P is supposed to be the starting point. The starting point of the ray should be the first point in the naming and the direction should follow towards the second point.
To correctly name the ray based on the visual representation, it should be \overrightarrow{PQ}, assuming point Q is extending indefinitely in the direction of point P. Therefore, Rohan is incorrect in naming the ray \overrightarrow{QP} for the given visual representation. It should be \overrightarrow{PQ} instead.
Rohan correctly named the ray as QP if Q is the starting point extending towards P. In geometry, naming a ray requires identifying the endpoint and direction clearly. Based on the visual representation provided, Rohan's naming could be right depending if Q is indeed the start.
