Incenter of the triangle is the center of point of concurrency where the three angles of the triangle bisect together. The incenter (intersection of angle bisectors) is the center of inner circle of the triangle. The angles are concurrent as they always meet in the interior of the triangle. Incenter is the point whose distance to the sides are equal. Simple geometry calculator which is used to calculate the incenter of a triangle based on two dimensional line.
If (x1, x2, x3) is (2,3,4) and (y1, y2, y3) is (1,6,2) and (a,b,c) is (4,1,7)
x = (2 * 4 + 3 * 1 + 4 * 7) / (4 + 1 + 7)
y = (4 * 1 + 1 * 6 + 7 * 2) / (4 + 1 + 7)
