AB has ratios 1,-2,3 and BC has -2,4,-6. A, B, C are:
Apoints of a right triangle
Bpoints of an equilateral one
Cpoints of a scalene triangle
Dthree collinear points
Answer & Solution
Correct answer: D. three collinear points
The ratios are proportional with factor -2, so AB is parallel to BC and B is shared, giving collinearity.
