# Thread: Help with Graphing Geometry

1. ## Help with Graphing Geometry

I feel stupid asking this considering everyone else seems to be asking questions that seem 10 times more difficult than this... but..

The question was: "Find a fourth point, D, so that a parallelogram is formed using the vertices A(0,-4), B(5,-3), C(-4,-3) and D in any order. Plot your points and draw the parallelogram in the coordinate plane"

Could someone here help me out?

2. Hello, de1043!

Find a fourth point $D$ so that a parallelogram is formed
using the vertices $A(0,-4),\; B(5,-3),\; C(-4,-3)\text{ and }D$ in any order.
Plot your points and draw the parallelogram in the coordinate plane.
There are three possible parallelograms.

I'll let you figure out how I located those points.
