If the vertices of a triangle \(\mathrm{ABC}\) are \(\mathrm{A}(1,2,3) \mathrm{B}(\mathrm{h},-3,0)\) and \(\mathrm{C}(-4, \mathrm{k},-1)\) and the centroid of the triangle is \(\left(5,-1, \frac{2}{3}\right)\) then triangle \(\mathrm{ABC}\) is
- A an obtuse angled triangle
- B an acute angled triangle
- C an isosceles triangle
- D a right angled triangle
Answer & Solution
Correct Answer
(A) an obtuse angled triangle
Step-by-step Solution
Detailed explanation
Given vertices of a tiangle \(\mathrm{ABC}\) are \(\mathrm{A}(1,2,3), \mathrm{B}=\) \((\mathrm{h},-3,0)\) and \(\mathrm{C}(-4, \mathrm{~K},-1)\) and controid of \(\varnothing \mathrm{ABC}\) is \(\left(5,-1, \frac{2}{3}\right)\) now…
