Centre of incircle
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 axis and innermost point of the grassfire transform of … WebSep 9, 2024 · Inradius The inradius ( r ) of a regular triangle ( ABC ) is the radius of the incircle (having center as l), which is the largest circle that will fit inside the triangle. Circumradius: The circumradius ( R ) of a triangle is the radius of the circumscribed circle (having center as O) of that triangle. Examples: Input: r = 2, R = 5 Output: 2.24
