Question

The incentre of the triangle with vertices ( 1 , 3 ) , ( 0 , 0 ) and ( 2 , 0 ) is:, 1 , 3 2, 2 3 , 1 3, 2 3 , 3 2, 1 , 1 3

A B = 3 - 0 2 + 1 - 0 2 = 2 B C = 0 - 0 2 + 2 - 0 2 = 2 A C = 0 - 3 2 + 2 - 1 2 = 2 So, triangle is equilateral triangle. So, the incentre is the same as the centroid. Incentre = 1 + 0 + 2 3 , 3 + 0 + 0 3 = 1 , 1 3
