Question

When the coordinates (1, 1), (4, 4), (7, 1), and (4, -2) are joined, which shape is formed?

Answer 1

A square. Try using a coordinates grid to work this out.

Answer 2

To visualize the shape better, it would be helpful to graph the points by hand or using software like MS Excel. By graphing, you will see that the shape being formed is a quadrilateral, specifically a diamond. 

Hope this answers the question. Have a nice day.
