question_answer
The equations of the sides of a triangle are \[x+y-5=0;\ \] \[x-y+1=0\] and \[y-1=0,\] then the coordinates of the circumcentre are [MP PET 1996]
A)(2, 1)
B)(1, 2)
C)(2, -2)
D)(1, -2)
Correct Answer:
A
Solution :
Since the triangle is right angled so the circumcentre will be the middle point of hypotenuse i.e. (2, 1).
