Question

Which of the following options shows the same property between a rectangle and a square?

• A. Both have only $1$ pair of parallel lines
• B. Both have all the angles of measure ${90}^{\circ }$
• C. Diagonals cut each other perpendicularly
• D. Both have all sides of equal length

Answer 1

The correct option is B Both have all the angles of measure ${90}^{\circ }$

$1)$ Rectangle and square have two pairs of parallel lines. So [A] is wrong.

$2)$ Both square and rectangle have all it's angles equal to ${90}^{\circ }$. So $\left[B\right]$ is correct. (see the figure)

$3)$ In a square, diogonals cut each other perpendicularly but not in a rectangle. So [C] is wrong.

$4)$ In a square, all sides are equal but in a rectangle only opposite sides are equal. So, [D] is wong.

SO, the correct answer is $\left[B\right]$.
