To sketch the vector $h+g$, we can sketch the vector $h$ and the vector $g$ so that their initial points coincide. Then we can complete the parallelogram. The resultant vector through the middle of the parallelogram is the vector $h+g$.

To sketch the vector $h+g$, we can sketch the vector $h$ and the vector $g$ so that their initial points coincide. Then we can use another copy of the vector $h$ and the vector $g$ to complete the parallelogram. The resultant vector through the middle of the parallelogram is the vector $h+g$.
