Construct a parallelogram ABCD such that l(BC) = 7 cm, m∠ABC = 40° , l(AB) = 3 cm.
उत्तर
Steps of Construction:
Step 1: Draw AB = 3 cm.
Step 2: Draw ∠ABX = 40°
Step 3: With B as the center and radius 7 cm, draw an arc cutting the ray BX at C.
Step 4: With C as centre and radius 3 cm, draw an arc.
Step 5: With A as the center and a radius of 7 cm, draw an arc cutting the previous arc at D.
Step 6: Join AD and CD.
Here, ABCD is the required parallelogram.
