Question

Assertion(A): If centroid and circumcentre of a triangle are known its orthocentre can be found.
Reason (R) : Centriod, orthocentre and circumcentre of a triangle are collinear

• A. Both A and R are individually true and R is the correct explanation of A
• B. Both A and R individually true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A Both A and R are individually true and R is the correct explanation of A

Centroid, orthocentre and circumcentre are collinear and centroid divides

the line joining orthocentre and circumcentre in the ratio $2:1$ so if any two points are given then this one can be found.

Hence option 'A' is the correct choice
