Question

Which of the following options does not belong to the process of locating the circumcentre of a triangle?

• A. Construction of perpendicular bisectors.
• B. None of the above.
• C. Construction of a triangle.
• D. Construction of angle bisectors.

Answer 1

The correct option is D Construction of angle bisectors.

Circumcentre is the point of concurrence of the perpendicular bisectors of the sides of the triangle.

So, to locate the circumcentre of a triangle, we need to construct the perpendicular bisector of all the sides of the triangle.

Hence option C is not needed in the process of locating the circumcentre of a triangle.
