Math Puzzle: Shape-Birding

In a parallel universe, former bird watchers have adopted a new indoor hobby: identifying polygons in geometric figures. They seek closed shapes with no holes, crisscrossing edges, or touching corners.

Participants trace existing line segments to find shapes with varying numbers of sides.

The puzzle asks solvers to identify a single seven-sided shape, considering rotations and reflections as identical.

Additionally, solvers need to find all five distinct six-sided shapes within the figure.
