Construct ΔNTS where NT = 5.7 cm, TS = 7.5 cm and ∠NTS = 1100 and draw incircle and circumcircle of it.
Steps of Construction:
1. Construct ΔNTS of given dimensions.
2.Draw bisectors on ∠T and ∠S.
3.The point of intersection as B.
4.Draw perpendicular on NT from B.
5. With B as center and length of perpendicular as radius, draw a circle.
6.Draw perpendicular bisectors of ST and TN.
7.The point of intersection is A.
8. With A as center, and AS as radius draw a circle.
