74. If orthocenter and circumcentre of triangle arerespectively (1, 1) and (3, 2), then theco-ordinates of its centroid are |
|
Answer» As we know that orthocentre, centroid and cricumcentre are collinear and centroid divides the line segment joining ortho centre and circumcentre in the ratio 2 : 1. If the points of orthocentre and circumcentre are(1,1)and(3,2)(1,1)and(3,2)respectively the co-ordinate of centroid is: (2.3+1.1/2+1,2.2+1.1/2+1)=(7/3,5/3) |
