Ex.8.2 Q.1

ABCD is a quadrilateral in which P, Q, R and S are mid-points of the sides AB, BC, CD and DA (see the given figure).

AC is a diagonal. Show that:

(1) SR || AC and SR =

(2) PQ = SR

(3) PQRS is a parallelogram.

(1) In ∆ADC, S and R are the mid-points of sides AD and CD respectively.

In a triangle, the line segment joining the mid-points of any two sides of the triangle is parallel

to the third side and is half of it.

So, SR || AC and SR = .................(1)

(2) In ∆ABC, P and Q are mid-points of sides AB and BC respectively.

Therefore, by using mid-point theorem,

PQ || AC and PQ = AC ..............(2)

Using equations 1 and 2, we obtain

PQ || SR and PQ = SR ……………. (3)

So, PQ = SR

(3) From equation 3, we obtained PQ || SR and PQ = SR

Clearly, one pair of opposite sides of quadrilateral PQRS is parallel and equal.

Hence, PQRS is a parallelogram.
