Circle Diagram with Angles for Math Education

This clear geometric diagram features a regular 17-sided polygon, commonly known as a heptadecagon, complete with its center and lines extending to each vertex. The illustration highlights two key angle measurements: an interior angle of 158 and 14/17 degrees, and a central angle measuring 21 and 3/17 degrees. It serves as an excellent visual resource for teaching and learning about polygon geometry, angle properties, and the mathematical principles behind regular shapes.
