The medial triangle of a triangleABC is the triangle whose vertices are located at the midpoints of the sidesI am to use vector techniques to prove that a triangle and its medial triangle have the same centroid, statingAB,AC, andBC of triangleABC. From an arbitrary pointO that is not a vertex of triangleABC, you may take it as a given fact that the location of the centroid of triangleABCis the vector (vectorOA + vectorOB + vectorOC)/3

each step of the proof.I don't know where to begin with Vector Proofs...
