Question

Example 7: Construct a quadrilateral ABCD when AB = 3.5 cm, BC = 6,5 cm, 2A = 75°, ZC
120° and ZD = 75°. Measure AD and CD​

Answer 1

First draw a line segment Ab=7.2 cm

Make angle 75 at point A

Open compass 4.3 cm and cut the angle line at point D

Open compass 5.8 cm and mark curve from point B

Open compass 6.3 cm and mark curve from point D

This curve cut the curve mark from point B at point C
