What are the different types of poison vines and how can they be identified?

There are several types of poison vines, including poison ivy, poison oak, and poison sumac. These plants can be identified by their distinctive leaves, which are usually in groups of three for poison ivy and poison oak, and in clusters of 7-13 for poison sumac. The leaves may also have a shiny appearance and serrated edges. It is important to avoid contact with these plants as they can cause skin irritation and allergic reactions.
