Hey,
I am struggling with one question in vector proofs.
If D, E, and F are the midpoints of the sides of a triangle ABC, prove that
OD + OE + OF = OA + OB + OC
I don't really understand what we are trying to prove here. My first thought was that from some origin, to the points D E and F added up, is the same distance from some origin to A B and C added up.
I would really apprcieate some help. Also are there any tips or techniques you can give for generally solving questions that ask for proof?
Thanks
