Question

I am not understanding incircle or incentre method how they do it. Please make me coecl about it.

Answer 1

In geometry, the incenter of a triangle is a triangle center, a point defined for any triangle in a way that is independent of the triangle's placement or scale. The incenter may be equivalently defined as the point where the internal angle bisectors of the triangle cross, as the point equidistant from the triangle's sides, as the junction point of the medial axisand innermost point of the grassfire transformof the triangle, and as the center point of the inscribed circle of the triangle.
