Answer:
It is quite simple.
Explanation:
Here it given PR = RQ
Also ang P=ang Q
RS is the median. That is the hard part for u, I know.
A median of a triangle divides it into 2 parts of equal area. So here it divides PQ into 2 equal parts as RS is the median.
So PS=QS
Ang P=Ang Q
PR=RQ
From all this we can say that Triangle PRS congruent Triangle QRS.
