TBQ - Determine the collinearity of the points — task. Maths CBSE Live product, Class 10 (2026-27).

Determine if the points \(A(1, 5)\), \(B(2, 3)\) and \(C(3, 1)\) are collinear.

Answer:

\(AB\) \(=\)

\sqrt{i}

\(BC\) \(=\)

\sqrt{i}

\(AC\) \(=\)

i \sqrt{i}

Here, \(AB + BC\) \(AC\)

Therefore, the points \((1, 5)\), \((2, 3)\) and \((3, 1)\) are .
