WebThe point of intersection of angle bisectors of the 3 angles of triangle ABC is the incenter (denoted by I). The incircle (whose center is I) touches each side of the triangle. In … WebSolution Given: In ΔABC,AD is the bisector of ∠BAC I is its incentre of ΔABC. To prove: AI I D = AB+AC BC Proof: Lets form a diagram, according to question. Since, in a triangle, the point of concurrence of angular bisectors is called an incentre. Here I is the incentre of ΔABC i.e., In ABD,BI is is the bisector of ∠ABD. dickies toys garbage truck
