Test: Understanding Quadrilaterals- 1 - Class 8 MCQ

Correct Answer :- b

Explanation:- A rhombus is a  parallelogram and a quadrilateral whose opposite sides are parallel and opposite angles are equal.

Area of Rhombus, A = (d1 x d2)/2

The perimeter of Rhombus, P = 4a units

The opposite angles of a rhombus are equal to each other.

In a rhombus, diagonals bisecting each other at right angles.

Diagonals bisect the angles of a rhombus

- When the sides of a triangle are extended, each exterior angle formed is the supplementary angle to the interior angle.
- The sum of the exterior angles of any polygon, including triangles, is always 360°.
- This is because each exterior angle is effectively a turn around the triangle, adding up to a full circle.
- Thus, regardless of the triangle's type, the sum of the exterior angles formed is 360°.
- Therefore, the correct answer is D: 360°.

Angle sum property of a triangle is that sum of 3 angles is 180º

Correct option is A.

It’s a property of parallelogram that opposite sides of a parallelogram are equal and parallel.

If two adjacent sides of a parallelogram are equal, then it is a rhombus.. A quadrilateral whose diagonals bisect each other at right angles is a rhombus.

In square all sides are equal and every angle is right angle.

Kite, is a quadrilaterals has two pairs of adjacent sides equal and diagonals intersecting at right angles. 

Pentagon have 5 sides .
