If two diameters of a circle intersect each other at right angles, then quadrilateral formed by joining their end points is a

Let AB and CD are two diameters of circle

∠AOD = ∠BOD = ∠BOC = ∠AOC = 90°


AB and CD are diagonals of quadrilateral ABCD


They intersect each other at right angles


And


AB = BC = CD = DA


We know that,


Sides of a square are equal and diagonals intersect at 90°


Therefore, ABCD is a square
