Question

The centroid and the orthocentre are coincident for which one of the following triangles$?$

• A. Scalene triangle
• B. Isosceles triangle
• C. Equilateral triangle
• D. Right angled triangle

Answer 1

Answer: (C)

Equilateral triangle

Centroid is point of intersection of medians of a triangle.

Orthocenter is point of intersection of three altitudes of a triangle.

For an equilateral triangle, the centroid and the orthocentre all lie at the same point and hence are concurrent.
