Answer 1

1st method

• at first draw the base line BC = 7cm ,by the properties of parallelogram side AD , will be equal and parallel to BC
• draw 40° angle at B with the help of protector mark and dashed line, extend the line. mark a point A at 3cm
• now angle C is adjacent to B ,∆c will be 180-40 = 140° , measure 140° angle from C , extends the line, mark D at 3cm ,since AB = CD
• join point C and D and A and D

2 nd method

• draw AB = 3cm
• draw ∆ABX = 40°
• with B as centre and radius 7cm draw an arc cutting the Ray BX at C
• with C as centre and Radius 3cm , draw an arc
• with A as a centre and Radius 7cm ,draw an arc cutting the previous arc at D
• join AD and CD
