Can a Quadrilateral ABCD be a Rhombus?

  • a) Angle A + Angle B = 180:

    In a rhombus, opposite angles are equal. If angle A and angle B add up to 180 degrees, they are not equal, therefore quadrilateral ABCD cannot be a rhombus based on this condition.


  • b) Angle B + Angle D = 180:

    Similar to the previous scenario, if angle B and angle D add up to 180 degrees, they are not equal. Hence, quadrilateral ABCD cannot be a rhombus in this case either.


  • c) Angle A = 2*Angle B and Angle D = 1/2*Angle A:

    If angle A is twice angle B and angle D is half of angle A, the angles are not equal in a way that would make ABCD a rhombus. Therefore, this condition does not support the quadrilateral being a rhombus.


  • d) AB = 3BC:

    In a rhombus, all sides are equal. If AB is three times the length of BC, then all sides cannot be equal, thus quadrilateral ABCD cannot be a rhombus with this condition.


Therefore, based on the conditions provided, quadrilateral ABCD cannot be a rhombus. Each condition fails to satisfy the properties of a rhombus, which includes having all sides equal in length and opposite angles equal.
