In a square PQRS, the diagonals bisects at O, Then \[\Delta \text{POQ}\] is _________.

A)  Equilateral

B)  Isosceles but not right angled

C)  Right angle but not Isosceles

D)  Isosceles right angled

Correct Answer: D

Solution :

Since, we know that diagonals of a square are equal and perpendicularly bisect each other. So, \[\angle POQ=90{}^\circ \text{ and }PO=OQ.\] Hence, AOPQ is isosceles right angled triangle.
