Question

Which of these is not a property of rectangle?

• A. Opposite sides are equal.
• B. Adjacent sides are perpendicular to each other.
• C. The diagonals are of equal length and intersect perpendicularly.
• D. The diagonals are of equal length and bisect each other.

Answer 1

The correct option is C The diagonals are of equal length and intersect perpendicularly.

The properties of rectangle are:
-Opposite sides are equal.
-All the internal angles are equal to ${90}^0$
-Adjacent sides are perpendicular to each other.
-Both the diagonals are of equal length and bisect each other.

But the diagonals of the rectangle are not perpendicular to each other.
