We have to find the coordinates of vertex E of parallelogram ACBE. First
we have to find the midpoint of a diagonal AB : xM = ( xA + xB ) / 2 = (
1 + 3 ) / 2 = 4 /2 = 2; yM = ( yA + yB ) / 2 = ( 2 + 6 ) / 2 = 8 / 2 =

  1. So the coordinates of the midpoint are M ( 2, 4 ). And it is also a

midpoint of another diagomal ( CE ). ( xE + 6 ) / 2 = 2; xE + 6 = 4; xE
= 4 - 6 = - 2. ( yE + 4 ) / 2 = 4; yE + 4 = 8; yE = 8 - 4 = 4.
Answer: The coordinates of vertex E are A ) ( -2, 4 ).
