The points (1,5), (4,5), and (1,0) represent three corners of a rectangle; find the coordinates of the fourth poin

• Algebra -

Those three coordinates should tell you that the rectangle has sides parallel to the x and y axes. This makes the problem simple. The first two points are the ends of a horizontal line at y =5, with length 3.

The first and third points are the ends of a vertical line at x=0 with length 5.

A point at (4,0) will complete the rectangle with a side at x=4 of length 5, and a side at y=0 with length 3.

If you can't follow my argument, try plotting the points on a graph.
