Question

a rhombus is a parallelogram in which ______ sides are equal​

Answer 1

Answer:

A Rhombus is a Parallelogram in which all four sides are equal.

Explanation:

• A Parallelogram in which all sides are equal is called a Rhombus.

• Its diagonals bisect each other at right angles.

(Refer the Attachment for the diagram)

Area of the rhombus ABCD

= Δ ADC + Δ ABC

= 2 Δ ADC

= 2 ( $\frac{1}{2} \times AC \times DO$ )

= AC x DO

= AC $\times \frac{1}{2} BD$

= $\frac{1}{2} \times AC \times BD$

And therefore, the area of a rhombus = $\frac{1}{2} \times$ product of their diagonals.

Answer 2

$\sf \:Answer$ :

A rhombus is a parallelogram in which all sides are equal.

$\sf\:Explanation$ :

In parallelogram opposite sides are equal in length and parallel as shown in the figure.

PQRS is a parallelogram where opposite sides(PQ,RS) and (QR,PS) are equal and parallel and when all sides of a parallelogram become equal then it is known as rhombus.
