Find the length of each side of the triangle determined by the three points P 1 ? ,P 2 ? , and P_3

Find the length of each side of the triangle determined by the three points P, , P,, and P. State whether the triangle is an isosceles triangle, a right triangle, neithe of these, or both. (An isosceles triangle is one in which at least two of the sides are of equal length.) P 1 = (4, - 5); P2 = (2, - 5); P3 = (4, - 3) The length of side P, P2 is (Type an exact answer, using radicals as needed)
