Polyhedra (singular: polyhedron)
No, the "U" shape is not a polygon. Polygons are closed figures made up only of line segments. The "U" shape includes a curved section, and is usually not a closed figure.

Spatial figure is a three dimensional figure. It is made up of plane figure whose all sides are joined together to form a close figure
A closed figure made from line segments that meet at their endpoints is known as a polygon. Polygons can have various numbers of sides, such as triangles (3 sides), quadrilaterals (4 sides), and so on. The points where the line segments meet are called vertices, and the segments themselves are referred to as edges or sides. Polygons can be classified as regular (with equal sides and angles) or irregular (with varying side lengths and angles).
A polygon is a closed figure made by joining line segments, where each line segment intersects exactly two others. Many figures are polygons, but take any polygon and remove and edge and you have a figure that is not a polygon. So the anwer is yet it can.
A closed shape that is not a polygon made entirely of segments is a circle. Unlike polygons, which are composed of straight line segments, a circle is defined as the set of all points equidistant from a central point, and its boundary is smooth and curved. Other examples include ellipses and certain types of curves, such as ovals or closed curves like a figure-eight. These shapes do not have the straight edges characteristic of polygons.
a polygon is a shape with 5 corners A pentagon has five sides. A polygon has 3 or more sides, is closed and has line segments as the sides ( no curved sides ).
They are called polygons
They are polygons which have 3 or more line segments
A closed figure made up of line segments is called a polygon. The segments in a polygon are called sides or edges.
