You can put this solution on YOUR website! Triangle ABC is defined by the vertices A (0,-6), B ( 1,0) and C (6,-7)
What type of triangle is ABC
AB DATA:
slope = (0--6)/(1-0) = 6
length = sqrt(6^2+1^2) = sqrt(37)
---
AC DATA:
slope = (-7--6)/(6-0) = -1/6
length = sqrt(1^2+6^2) = sqrt(37)
----------------------------------------
What type of triangle is ABC
Ans: Isosceles Right Triangle.
