Construct A Parallelogram given sides and angle
Construct a parallelogram ABCD with sides AB = 4 cm and AD = 5 cm and angle A = 60˚.
Step 1: Construct a line segment AB = 4 cm. Construct a 60˚ angle at point A.
Step 2: Construct a line segment AD = 5 cm on the other arm of the angle. Then, place the sharp point of the compasses at B and make an arc 5 cm above B.
Step 3: Stretch your compasses to 4 cm, place the sharp end at D and draw an arc to intersect the arc drawn in step 2. Label the intersecting point C. Join C to D and B to C to form the parallelogram ABCD.
