Answer: 1 Mark

The angle covered when the minute hand moves from 3 to 6 is 90 degrees.

Given that:

The sides of the quadrilateral are equal.
So the triangle can either be a rhombus or a Square.
But the angles included between the sides is 90${}^{\circ }$.
$\therefore$ The quadrilateral is a Square.

Now in a square, the diagonals intersect each other at 90${}^{\circ }$.
