# Creating 3 Lines to Form a Right Triangle

- Author:
- Tim Brzezinski

Creation of this resource was inspired by an Open Middle problem from Tracy Conte.

## Directions: Using integers -9 to 9 at most one time each, fill in the boxes to create three lines that form a right triangle on the coordinate plane.

## Even though the angles may show you have a right triangle above, algebraically show why you know your setup above is valid.

## Same task as above, yet this time create ANOTHER SETUP that is ENTIRELY DIFFERENT from the one you created above. Be sure not to repeat digits!
