Yes
Polygons have sides made of line segments (straigh lines). There are no line segments in a circle.
They are polygons which have 3 or more line segments
polygons
NO, a circle is not a polygon. A polygon is composed of a finite set of straight line segments, and a circle has NO straight line segments.
a quadrilateral and other polygons
polygons
triangles , polygons ,quadrilaterals
Many polygons, such as squares, rectangles, rhombi, parallelograms, etc. have more than 1 pairs of parallel line segments. Trapezoids have only 1 pair of parallel line segments. These few shapes are just quadrilaterals, other polygons also have more than 1 pair of parallel line segments (e.g. regularhexagons, octagons, etc.). Triangles never have any parallel line segments.
wat do you mean
None in the Roman alphabet.
The letter "H" can be used to create four polygons by drawing four line segments. By connecting the top and bottom horizontal lines and the two vertical lines in the center, you can form a square, two triangles, and a rectangle. Each of these shapes is considered a polygon, as they are closed figures with straight sides.
A bell is a shape, but not a polygon. Polygons are constructed only from straight line segments, they do not contain curves (a circle is not a polygon either, unless you imagine it as being composed of infinitely many line segments, each of which is infinitely short).
