Given is the triangle OAB and a variable point P. G is the centroid. Prove that:
The Attempt at a Solution
I treat O as the origin.
Vectors are denoted in bold.
Position vectors of A, B, P are a,b and p respectively.
How on earth am I going to prove that:
I mean is there any criteria to prove this equation in modulus of vectors when I dont know the angles between any of them?
