Question 1027175
3 points of a triangle are given. Use the points to draw the triangle, then use the slope formula to determine if any of the triangles are right triangles.
(0,0) (-5,2) (2,-5)
*I have done this problem over 10 times and can't figure out if it's a right triangle or not, I have to answer it correctly by tomorrow for class so if someone can please tell me if it forms a right triangle or not I'd highly appreciate it!!!
<pre>Easiest method: Determine the slopes.
Slope of AB: - .4
Slope of AC: - 2.5
Slope of BC: - 1
No 2 slopes are negative reciprocals of each other, so no 2 slopes are perpendicular, hence, this is NOT a right triangle
