Work Step by Step

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