Find the length of each of the sides of the triangle using the distance formula.

d=sqrt%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29

If the lengths of any two sides are equal, then the triangle is isoceles by definition. Strictly, you should show that the third side is not equal to the other two.
