Solve the problem.Find the length of each side of the triangle determined by the three points P1, P2, and P3. State whether the triangle is an isosceles triangle, a right triangle, neither of these, or both.P1 = (-5, -4), P2 = (-3, 4), P3 = (0, -1)
A. d(P1, P2) = 2
; d(P2, P3) = 
; d(P1, P3) = 
both
B. d(P1, P2) = 2
; d(P2, P3) = 
; d(P1, P3) = 5
right triangle
C. d(P1, P2) = 2
; d(P2, P3) = 
; d(P1, P3) = 5
neither
D. d(P1, P2) = 2
