Problem

If CC is the mid-point of ABAB and PP is any point outside ABAB, then (1) PA+PB+PC=0\mathbf{PA} + \mathbf{PB} + \mathbf{PC} = 0 (2) PA+PB+2PC=0\mathbf{PA} + \mathbf{PB} + 2\mathbf{PC} = 0 (3) PA+PB=PC\mathbf{PA} + \mathbf{PB} = \mathbf{PC} (4) PA+PB=2PC\mathbf{PA} + \mathbf{PB} = 2\mathbf{PC}
