Question

In the figure given below, BDEF and DCEF are two parallelograms. Show that BD = DC.​

Answer 1

Answer:

firstly draw a line AB of 7.28cm and then increase 1 unit more from point B to C and then taking C as a centre draw a semi-circle from A to C and then at point B draw a perpendicular from point F and this perpendicular line is equal to √7.28 and cut an arc from point B on the number line.

Answer 2

It is given that BDEF and FDCE are parallelograms. ⇒ BD = FE ….(i) (opposite side of parallelogram are equal) Also DC = FE …(ii) (reason as above) ⇒ BD = CD
