Question

Construct a parallelogram ABCD given, AB= 4cm, BC= 5.2cm,angle ABC=120degree​

Answer 1

steps of construction :

draw a rough sketch and label it with all measurements

draw a linesegment of BC of 5.2 cm as a base

taking more than half of the BC draw a semi circle mark as O

taking center as O draw an arc without changing radius . mark it as K

taking k as center draw another arc of same radius

mark it as H

it is 120 degrees

it is with compass if u want with protractor draw directly the angle 120 degrees taking point as B draw a n arc of radius 4 cm it is AB mark it as A

as it a parllogram some of opp sides are equal and angles on same plane add upto 180 degrees
