Question

Draw a Parallelogram ABCD such that BC = 4.5 cm, BD = 4 cm and AC = 5.6 cm.​

Answer 1

Step-by-step explanation:

Steps of Construction:

(i) Draw a triangle BOC with BC = 4.5 cm

Here

BO = ½ × 4 = 2 cm

OC = ½ AC

= ½ × 5.6

= 2.8 cm

We know that the diagonals of a parallelogram bisect each other.

(ii) Produce OC to point A such that OC = OA.

(iii) Produce BO to point D such that OD = OB.

(iv) Now join AD.

Therefore, ABCD is the required parallelogram
