Question

Choose the correct option(s) regarding rectangles:

• A. A rectangle is a parallelogram with all sides equal.
• B. All angles in a rectangle are equal to ${90}^{\circ }$.
• C. All angles in a rectangle are equal to ${180}^{\circ }$.
• D. Diagonals of a rectangle are not equal.

Answer 1

The correct option is B All angles in a rectangle are equal to ${90}^{\circ }$.

In rectangle opposite sides are equal. So option A is wrong.
All the angles in a rectangle are equal to ${90}^{\circ }$ and not ${180}^{\circ }$. So option C is wrong.
In a rectangle diagonals are equal in length. So option D is also wrong.
A rectangle is a parallelogram with all angles equal to ${90}^{\circ }$. So, option B is the right answer.
