Ex.8.2 Q.5

In a parallelogram ABCD, E and F are the mid-points of sides AB and CD respectively (see the given figure).

Show that the line segments AF and EC trisect the diagonal BD.

ABCD is a parallelogram.

So, AB || CD

And hence, AE || FC

Again, AB = CD

(Opposite sides of parallelogram ABCD)

=> =

=> AE = FC

(E and F are mid-points of side AB and CD)

In quadrilateral AECF, one pair of opposite sides (AE and CF) is parallel and equal to each other.

Therefore, AECF is a parallelogram.

AF || EC (Opposite sides of a parallelogram)

In ∆DQC,

F is the mid-point of side DC and FP || CQ

(As, AF || EC).

Therefore, by using the converse of mid-point theorem, it can be said that P is the mid-point of DQ.

So, DP = PQ ...............(1)

Similarly, in ∆APB,

E is the mid-point of side AB and EQ || AP

(As, AF || EC).

Therefore, by using the converse of mid-point theorem, it can be said that Q is the mid-point of PB.

So, PQ = QB ...............(2)

From equations (1) and (2),

DP = PQ = BQ

Hence, the line segments AF and EC trisect the diagonal BD.
