Question

Sides of a triangle ABC are equidistant from the centre O of its circumcircle. Triangle ABC is

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

Answer 1

The correct option is A

Equilateral triangle

OL = OM = ON

Therefore, chords BC, CA and AB of the circle are equidistant from the centre.

Hence, BC = CA = AB (equidistant chords from the centre are equal)

Thus, ABC is an equilateral triangle.
