Question

Let G be the Centroid of triangle ABC with sides a, b, c. If P be any point in the plane of triangle ABC such that PA=2, BP=5, PC=6 and PG=4 then find a^2 +b^2 +c^2. ​

Answer 1

Step-by-step explanation:

ABC is a triangle with vertices A(–3,2), B(3,2) and C(–2, –3) and D, E and F are the

midpoints of the sides BC, CA and AB respectively then prove that the centroid of the

triangle ABC coincides with
