Question

Construct a parallelogram ABCD such that l(BC) = 7 cm, m∠ABC = 40°, l(AB) = 3 cm.

Answer 1

Hi,

Solution:

Steps of construction:

• At first Draw the base line BC = 7 cm,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 dashed line, extend the line . mark a point A at 3 cm.
• Now angle C is adjacent to B, ∠C will be 180-40 = 140°,measure 140° angle from C ,extend the line,mark D at 3 cm,since AB = CD
• join point C and D and A and D.

hope it helps you.
