To accurately identify the mathematical name of the shaded polygon, I would need a description or visual representation of the polygon in question. Polygons are named based on the number of their sides, such as triangle (3 sides), quadrilateral (4 sides), pentagon (5 sides), hexagon (6 sides), and so on. If you provide more details, I can help determine the specific name.
