    Given points ,

    A(5,0) , B(11,0) & C(8,4)

    the distance between A and B =√(x2-x1)^2 + (y2-y1)^2

    √(11-5)^2 + (0-0)^2

    √6^2 =6

    therefore , the distance between A and B = 6 units

    similarly ,

    the distance between B and C = 5 units

    the distance between C and A = 5 units

    from the above ,

    CA = BC ≠AB

    hence , the given points are the vertices of a isosceles triangle
