If the vertices of a triangle are `(sqrt5,0)` and `(sqrt3,sqrt2)`, and `(2,1)` then the orthocentre of the triangle is

A

`(sqrt5,0)`

B

`(0,0)`

C

`(sqrt5+sqrt3+2,sqrt2+1)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
The circumcenter of the triangle is (0,0) as vertices are at equal distance from (0,0). So, the orthocenter will be (sum of x-coordinates, sum of y-coordinates).
