When they meet at right angles when plotted on the coordinated grid.
Use the Pythagorean Theorem.
Count the number of grid squares which are entirely or almost entirely inside the figure = ACount the number of grid squares which are approximately half (or more) inside = B Estimated area = A + B/2.
It is the point of origin at (0, 0) where the x and y axes meet each other at right angles
Points on a grid? It would then be x,y and z coordinates
