Question 895807: Find 4th vertex of a quadrilateral whose three vertices are (0,0), (2,0) and (0,3).
Answer by josgarithmetic(39616)   (Show Source):
You can put this solution on YOUR website! The fourth vertex could be almost anywhere in the quarter plane, specifically in the quadrant 1, and NOT on the x-axis nor y-axis. Also, you probably want  and  . In fact, the choices are greater than that, since you can allow for a concave quadrilateral, so ANY point chosen can be a possibility as long as it is not one of the three points you already gave.
As an example, (3,3) will work; as well as (2,3).
