Question

Three of the vertices of a parallelogram are (2, 1) (4, 7), and (6, 5).

What are the three possible coordinates of the fourth vertex?

Answer 1

please help me

Answer 2

thanks you pellets for nothing.

Answer 3

do you know the distance formula?

Answer 4

suppose the 4th vertex as (x,y)

Answer 5

then using distance formula find the two equations containing x,y then solve them

Answer 6

Graph the three given points on the graph paper, then use translation (gliding) to find the three possible coordinates of the 4th vertex, namely
(4, -1), (0, 3), and (8, 11)
