Question

If opposite angles of a parallelogram are supplementary, then the parallelogram is -

• A. Trapezium
• B. rectangle
• C. rhombus
• D. Hexagon

Answer 1

The correct option is B

rectangle

Opposite angles of a parallelogram are necessarily equal.

If they are supplementary as well, then it means that each angle will be equal to ${90}^{\circ }$.

A parallelogram having all its internal angle as ${90}^{\circ }$ is a rectangle.

Thus, the parallelogram is a rectangle.
