= Geometric Proofs... = === Group 5: Create a right angle triangle that has no side parallel to an axis (i.e. tilted) and prove it is a right angle triangle using both the side lengths and slope. === ===** Natalie & Amanda: ** ===

We created a right angle triangle that has no side parallel to an axis. The points were D(1,4) F (-2,2) E(3,1). To verify that it was a right angle triangle, we checked the side lengths and the slope. The slope of DE and FD were negative reciprocals.

** Steps: **
1) Check the 3 slopes of the triangle using the formula - __y2 - y1__ x2 - x1 2) Check that two slopes are negative reciprocals. 3) Check side lengths, you should be able to apply the pythagorean theorum (a2 + b2 = c2) to the right angle triangle.
