Determine if triangle def with coordinates d (2, 1), e (3, 5), and f (6, 2) is an equilateral triangle. use evidence to support your claim. if it is not an equilateral triangle, what changes can be made to make it equilateral? be specific.

The question is asking to determine of the said triangle that has the corresponding coordinate is an equilateral triangle and in my own calculation and plotting the said coordinates, I would say  that the answer would be that the triangle is not an equilateral but an Isosceles triangle. I hope you are satisfied with my answer and feel free to ask for more
