Question on straight lines- find the possible co-ordinates.

Dear Student

One additional information is needed to find the coordinates of  vertex A

it could be either the length of median from A to BC or distance of circumcentre to the vertex or centroid. Pls check

Let coordinates of A be (h_, k)

Circumcentre G     = (0, 0)   (Given)

Orthocentre  = (9, 5)    (Given)Equation of BC= 2 x –y = 10 Slope of line perpendicular to it is -1/2
