Question

If the diagonals of quadrilateral bisect one another at right angles, then the quadrilateral ls a

• A. Trapezium
• B. Rectangle
• C. None of these
• D. Rhombus

Answer 1

The correct option is D Rhombus

If the diagonals of quadrilateral bisect one another at right angles, then the quadrilateral is a Rhombus.
Rhombus has the following properties:

• Opposite angles of a rhombus have equal measure.
  
• The two diagonals of a rhombus are perpendicular; that is, a rhombus is an orthodiagonal quadrilateral (In geometry, an orthodiagonal quadrilateral is a quadrilateral in which the diagonals cross at right angles)..
  
• Its diagonals bisect opposite angles.
