Detailed Solution

The parallelogram circumscribing a circle is a rhombus.
Given that a parallelogram circumscribes a circle with center

O

Assuming that

ABCD

is a parallelogram,

A B = B C = C D = A D

[Given]
Tangents drawn are equal if they are from the same external point, therefore

AP = AS … … (i) BP = BQ … … (ii) CR = CQ … … (iii) DR = DS … … (iv)

Adding

AB

and

CD

AB + CD = AP + BP + CR + DR = AS + BQ + CQ + DS

[From (i), (ii), (iii) and (iv)]

= (AS + DS) + (BQ + CQ) AB + CD = AD + BC

We use the parallelogram property which states that the opposite sides of a parallelogram are equal.

2 AB = 2 AD AB = AD CD = AB = AD = BC

Thus, the parallelogram circumscribing a circle is a rhombus.
