I would use the distance formula to find the length of each side.

If all three are the same, it is equilateral.

joannablackwelder · Answer

2 sides the same is isosceles.

joannablackwelder · Answer

Right triangle would follow the formula a^2 + b^2 = c^2

joannablackwelder · Answer

Scalene is if none of them are the same, but it's not a right triangle.
