Explanation:
Follow the coordinates of each letter so A =7,0 which means you go 7 across and dont move up and you label that A. And then you move to B which is 3,1. so you go 3 across and 1 up and you label that B. and so on. Until you get a quadrilateral shape. it can either be a square, rectangle, rhombus, kite or whatever. im not 100% sure with this. But i know the coordinates.
