The incentre of the triangle with vertices (1,3), (0,0) and (2, 0) is
1,32
23,13
23,32
1,13
Let A(1, 3), B(0, 0) and C(2, 0) be the vertices
of ∆ ABC. Then
a=BC=2, b=AC=2 and c=AB=2
⇒ AB=BC=CA
⇒ △ABC is equilateral
Hence, the incentre is same as the centroid whose coordinates are
1+0+23,3+0+03≡1,13
