plz mark me as brain list

Step-by-step explanation:

• Given : AB = 6 cm, BC = 4 cm. and ∠B = 120° To construct: Incircle of ΔABC Steps of construction : (1) Draw a line segment BC = 4 cm. (2) Construct a ray making an angle of 120° at B of BC. Cut AB = 7 cm. (3) Join A to C, and obtain ΔABC. (4) Now bisects ∠ABC and ∠BCA that to intersect at O. (5) Draw OD ⊥ AC and with O as centre and OD as radius draw a circle which touches three sides ΔABC. This is the in circle of ΔABC.Read more on Sarthaks.com - https://www.sarthaks.com/762658/draw-a-abc-in-which-ab-6-cm-bc-4-cm-and-angle-b-120-construct-an-incircle-of-this-triangle
