Question

Diagonals of a rectangle are_____.

• A. equal
• B. distinct
• C. parallel
• D. perpendicular

Answer 1

Answer: (A), (D)

The correct options are
A equal
D perpendicular

Let us take rectangle $ABCD$ with $AC$ and $BD$ diagonals intersecting at $O$.

We assume that $AC$ and $BD$ are perpendicular to eachother.

Then, $\angle AOB$ & $\angle AOD$ should be equal $={90}^o$

For that $AB=AD$

But it is not necessary for any rectangle except the rectangle is a square.

$\therefore$ the diagonals need not be perpendicular to eachother.
