There are many isosceles triangles with the coordinates (0,0),(a2,a),(a2,-a) [where a is a positive number].
However there is only one equilateral triangle with vertices (0,0),(3,√3),(3,-√3).
Length of the side = √12
there is a isosceles triangle inside a parabola y2=x, with one vertex (0,0), than find the length of the sides of triangle
there can be many.. perhaps you are talking about equilateral triangle and not isosceles.
