Answer 1

Answer:

Show that if the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus. Sol: We have a quadrilateral ABCD such that the diagonals AC and BD bisect each other at right angles at O. Their corresponding parts are equal. Thus, the quadrilateral ABCD is a rhombus.
