Question

4. Construct a quadrilateral DNSI in which DN = 2.5 cm, NS = 3.7 cm and
ZI = 60°, ZN = 120°, ZS = 90°.​

Answer 1

First draw angle S which is 90 degrees using special angle construction where you first draw an arc and then keep the compass point at zero degrees and cut an arc where the pencil meets e circular arc . This will be the sixty degree angle . Don’t change the radius . Follow the same for 120 degrees but keep the compass point at 60 degrees which you’ve drawn .
Then draw the respective measures and join them
