Consider the following for the next two (02) items:
An equilateral triangle ABC is inscribed in a circle of radius 20√3 cm.
The centroid of the triangle ABC is at a distance d from the vertex A. What is d equal to?
Elementary MathematicsGeometry: Lines, Angles and Triangles
- A15 cm
- B20 cm
- C20√3 cm
- D30√3 cm
Explanation
In an equilateral triangle the centroid coincides with the circumcentre, so its distance from any vertex equals the circumradius: d = 20√3 cm.
