A closed plane figure which is bounded by straight sides.
A polygon is a closed figure bounded by sides. A triangle is a closed figure bounded by three sides. Therefore, according to the definition of polygon triangle is a polygon.
A polygon is a plane closed shape that is bounded by straight lines. A figure that is not a polygon is one the does not satisfy all three requirements.If the boundaries of the shape move in three (or more) dimensions then it cannot be a polygon. For example, consider a die, ABCDEFGH where the square EFGH is directly under ABCD. Then ABCGHDA is a closed figure, bounded by straight lines but it is not a plane figure.If ABCD is a square, then ABC is not a polygon because it is not closed.A circle, ellipse, semicircle, a squiggle are not polygons because they are bounded by sides that are no all straight.

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 ).

A polygon
A Polygon is a closed plane figure bounded by straight sides.Polygons is a plane figure with more than 3 straight sides and angles and are typically 5 or more.
A polygon must be a plane, closed figure bounded by straight lines.
A closed plane figure which is bounded by straight sides.
A closed 2-dimensional figure bounded by straight lines. A polygon can have three or more sides.
It is a 2-dimensional (plane) figure that is closed and which is bounded by straight lines.
A polygon is a closed figure bounded by sides. A triangle is a closed figure bounded by three sides. Therefore, according to the definition of polygon triangle is a polygon.
A polygon is any closed plane figure bounded by three or more straight sides.
It must be a plane figure. It must be closed. It must be bounded by straight lines. These straight lines must not cross one another.
Starting with the definition of polygon makes much easier to understand why triangle is a polygon.Definition: A polygon is a closed figure bounded by sides.Definition of triangle: Triangle is a closed figure bounded by three sides.Since triangle is also a closed figure bounded by sides therefore, triangle is a polygon.
polygon is a closed figure which is bounded by line segments.
