Webb3 dec. 2015 · 2 Answers. If you have already proven this theorem, you can reference it and it is a fine proof. If you have not already proven it, you need to do so. By cutting the parallelogram into four triangles by the diagonals and showing that the triangles are congruent if the diagonals are, you can get there. There are other approaches as well. WebbIf you just add by putting the head to tail of the two vectors and you construct a triangle, the parallelogram just helps us appreciate that you can start with the yellow vector and then the blue vector or the blue vector first and then the yellow vector. But either way, the sum is going to be this vector C. Up next: exercise.
