Answer
Vertex $O$ is at $(0, 0)$.
Vertex $S$ has coordinates $(0, h)$.
Vertex $W$ has coordinates $(b, 0)$.
Vertex $T$ has coordinates $(b, h)$.
Work Step by Step
Vertex $O$ is at the origin at $(0, 0)$.
Vertex $S$ has no $x$ value, but the $y$ value is equal to the height $h$. Therefore, vertex $S$ has coordinates $(0, h)$.
Vertex $W$ has an $x$ value equal to the base $b$, but there is no $y$ value. Therefore, vertex $W$ has coordinates $(b, 0)$.
Vertex $T$ has an $x$ value equal to the base $b$ and a $y$ value equal to the height $h$. Therefore, vertex $T$ has coordinates $(b, h)$.
