Question

Which of the following is a true statement about quadrilaterals?

• A. A quadrilateral has 5 sides.
• B. In a quadrialateral, all angles are right angles.
• C. All sides are equal in a quadrilateral.
• D. A quadrilateral has 4 sides.

Answer 1

The correct option is D A quadrilateral has 4 sides.

The first option is, "A quadrilateral has 4 sides".
For a closed figure to be a quadrilateral, it should have 4 sides'.

Hence, this is true.

The second option is, "All sides are equal in a quadrilateral".
Only squares and rhombus have all sides equal.

Hence, this is not true.

The third option is, "In a quadrilateral, all angles are right angles".

In parallelograms other than squares and rectangles, adjacent angles will vary.


Hence, this is not true.

The last option is, "A quadrilateral has 5 sides".
This is not true, since, all quadrilaterals have 4 sides.
