The distance from the center of in-circle to the vertex of the triangle which is farthest from this center is
- The lengths of the sides are given as 5,12 and 13. Now we can see that the sides of the triangle follows pythagorean theorem as
- So the triangle is right angled triangle.
- Now the inradius ,r = = 2
- Now let the vertices are A,B and C ad the incentre is I. So AI = r/sin(A/2)
- Now putting the values of r and calculating A/2 from trigonometry we get AI = 2
