Coordinate Geometry Question 167

Question: The orthocentre of the triangle with vertices $ ( 2,\frac{\sqrt{3}-1}{2} ) $ , $ ( \frac{1}{2},-\frac{1}{2} ) $ and $ ( 2,-\frac{1}{2} ) $ is

[IIT 1993]

Options:

A) $ ( \frac{3}{2},\frac{\sqrt{3}-3}{6} ) $

B) $ ( 2,-\frac{1}{2} ) $

C) $ ( \frac{5}{4},\frac{\sqrt{3}-2}{4} ) $

D) $ ( \frac{1}{2},-\frac{1}{2} ) $

Show Answer

Answer:

Correct Answer: B

Solution:

Here, the given triangle is a right angled triangle at the vertex $ ( 2,-\frac{1}{2} ) $ .

Hence the orthocentre is at $ ( 2,\frac{-1}{2} ) $ .
