<PRE><B>Question 1038164</B>
Find the fourth vertex of a quadrilateral whose three vertices are (0,0), (2,0) ,and (0,3). 
-----
Plot the three points:: (0,0), (2,0), (0,3)
-----
Note:: (0,0) to (0,3) is a vertical line
Draw a vertical line at (2,0):: x = 2
-----
Note:: (0,0) to (2,0) is a horizontal line
Draw a horizontal line at (0,3):: y = 3
----
The vertical and the horizontal lines meet at (2,3)
That is the 4th vertex.
