Question:
Three points A, B, C are said to be collinear (with B between A and C) precisely when:
$AB=BC$ $AB+BC=AC$ $AB \times BC = AC$ $AB-BC=AC$
Step-by-Step Solution
Key Concept: This is the standard distance-based collinearity test used in the current syllabus (since the coordinate area-of-triangle test has been removed).
Collinearity with $B$ between $A$ and $C$ is confirmed exactly when the sum of the two smaller segments equals the full segment: $AB+BC=AC$. [1.0 Mark]
Correct Answer:$AB+BC=AC$
