SUMMARY

The discussion focuses on proving the Appolonius theorem for triangle ABC with vertices at points A(-a, 0), B(a, 0), and C(b, C) on the Cartesian plane. The theorem states that for any triangle, the sum of the squares of the lengths of two sides is equal to twice the square of the median length plus twice the square of the length from the median to the opposite vertex. The formula presented is a^2 + b^2 = 2(1/2 c)^2 + 2d^2, where d represents the length of the median intersecting side c.

Prove the theorem (Appolonius) for the triangle ABC where A, B, C are the respective points (-a,0), (a,0), (b,C) on the cartesian plane.

Would i do this using vectors in component form otherwise i have no idea how to do it?

what does the theorem say?
 
a^2 + b^2= 2(1/2 c)^2 + 2d^2

where d is the median intersecting c
