Question
If the vertices P, Q, R a triangle PQR are rational points, which of the golloeing points of the triangle PQR is / (are) always rational point (s)
(A rational point is a point both of coordinates are rational numbers)
(A rational point is a point both of coordinates are rational numbers)
Options
A.centroid
B.incentre
C.circumcentre
D.orthocentre
Solution
Since, the coordinates of the centroid are
, then the centroid is always a rational point.
, then the centroid is always a rational point.Create a free account to view solution
