For it to be a right triangle, it must have a right angle.
Right angles are formed by perpendicuar lines.
If we find that two of these lines are perpendicular, we will know it is a rt. triangle.
Perpendicular lines have slopes which are opposite reciprocals (like 3 and -1/3)
To find the slope between two points, use the formula
.
For line AB:
For line AC:
For line BC:
-2 and 1/2 are opposite reciprocals, so this must be a right triangle.

</em><em>Another way to do this would be to use the distance formula to find the three side lengths and see if the Pythagorean Theorem applies.</em>
