Options
- A. Vertices of an equilateral triangle
- B. Vertical of an isosceles triangle
- C. Collinear
- D. None of the above
Answer
C. Collinear
Step-by-step solution
According to question, Let find slope of A B, B C and C A Slope of A B= 1-3 1-(-2) = -2 3 Slope of B C= 3- ( 5 3 ) -2-0 = -2 3 Slope of C A= 5 3 -1 0-1 = -2 3 Since, slope of all lines are same, therefore, points are collinear.
