A) Collinear
B) Vertices of an equilateral triangle
C) Vertices of an isosceles triangle
D) None of these
Correct Answer: A
Solution :
[a] Here, \[\frac{\left( 3-\left( -2 \right) \right)}{1-3}=\frac{-6-4}{-2-(-6)}=\frac{-8-7}{-2-(-8)}\] \[\Rightarrow -\frac{5}{2}=-\frac{5}{2}=-\frac{5}{2}\]. Obviously, points are collinear.You need to login to perform this action.
