Two diameters of a circle intersect each other at right angles. Prove that the quadrilateral formed by joining their end-points is a square.

If two diameters of a circle intersect each other at right angles,then quadrilateral formed by joining their end points is a rhombus (b) rectangle (c) parallelogram (d) square

If two diameters of a circle intersect each other at right angles, then quadrilateral formed by joining their end points is a (a) rhombus (b) rectangle (c) parallelogram (d) square

The diagonals of a rectangle intersect each other at right angles. Prove that the rectangle is a square.

If the diagonals of a quadrilateral bisect each other at right angle, prove that the quadrilateral is a rhombus.

Prove that the quadrilateral formed by joining the mid-points of the sides of a square is also a square.

Show that the quadrilateral,formed by joining the mid-points of the sides of a square,is also a square.

If diagonal of a quadrilateral bisects each other at right angles then it is a

If diagonals of a quadrilateral bisect each other at right angles, then it is a :
