Detailed Solution for Test: Understanding Quadrilaterals- 1 - Question 1

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

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

Diagonals bisect the angles of a rhombus

Test: Understanding Quadrilaterals- 1 - Question 2

If the sides of a triangle are produced in order,What is the sum of the exterior angles so formed?

Detailed Solution for Test: Understanding Quadrilaterals- 1 - Question 2

- 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°.
