Use slope to show that ABC with vertices A (0,2) , B(2,3), and C (1,5) is a right triangle.
ok i know how to find slope.. its y2 - y1 / x2 - x1.....i already know that. but u c now there are 3 y and 3 x.
so wht...i did it myself. did i do it right. i think its not.
slope - 3 - 2 / 2- 0
slope - 1 / 2
and then i did.
slope - 5 - 3 / 1 - 2
slope - 2 / -1
wht to do?
