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.

evidence as in using the distance formula.

and solve it. all three sides:

fd is 17
