Answer 1

(-1,-1)

1. Explanation:

The square needs to be all side with the same value when you graph the vertices on x-y plot, you obtain (x is the dot that correspond a vertice and y the forth vertice )

x 2 | x

1 |

|

-2 -1 | 1 2

y -1| x

-2 |

If you draw a line between vertices the value it will be 2 + (-1) so the forth vertice has to be (-1,-1)
