What is a line polygon?
A polygon is a closed figure where the sides are all line segments. Each side must intersect exactly two others sides but only at their endpoints. The sides must be noncollinear and have a common endpoint. A polygon is usually named after how many sides it has, a polygon with n-sides is called a n-gon.
What is the meaning for polygon and the example?
A polygon is a closed shape with straight sides. Rectangles, triangles, hexagons, and octagons are all examples of polygons. The word polygon comes from the Greeks, like most terms in geometry, which they invented. It simply means many (poly) angles (gon).
Why is a line not a polygon?
Made of three or more straight line segments. But, two line segments forming a line are also a “poly” of a “gons” due to not having just one segment. So, I intuitively I as a non mathematician understand simple line segments with “more than one” gon/segment as a “polygon”.
What are the line segments of a polygon?
The line segments that form a polygon are called the sides of the polygon. A point where two sides meet is a vertex (plural form is vertices).
What is a polygon with 5 line segments?
A polygon made up of five line segments is called as pentagon and so on…. Sides of a polygon: The line segments forming the polygon are called its sides. Vertex or vertices: The end points of the line segments are called its vertices.
What is the difference between convex polygon and concave polygon?
Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
How do you describe a polygon?
A polygon is any shape made up of straight lines that can be drawn on a flat surface, like a piece of paper. Such shapes include squares, rectangles, triangles and pentagons but not circles or any other shape that includes a curve.
Is a polygon a straight line?
5 Answers. The line is a polygon in computing, since it is composed of 3 or more points, connected by straight lines. The computer doesn’t have to understand whether they are on a single line. According to most definitions of a polygon in geometry, polygons are 2-dimensional shapes.
How do you determine if a figure is a polygon?
A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon.
How do you describe a line segment?
It has no endpoints and extends endlessly in both directions. If you mark two points A and B on it and pick this segment separately, it becomes a line segment. The length of this line segment is the distance between its endpoints A and B. So, a line segment is a piece or part of a line having two endpoints.
What is the meaning of line segment?
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints.
What makes something a polygon?
In geometry, a polygon is a plane figure bounded by a finite sequence of line segments, a two-dimensional polytope. The line segments that make up the polygon are called sides; their intersections are called vertices.
What are polygons math?
Kids Math. Polygons. A polygon is a flat figure that is made up of straight lines and is enclosed. A few notes on the definition of a polygon that hopefully will help you remember: Flat – this means it’s a plane figure or two-dimensional. Straight lines – these are called segments in geometry.
What is a polygon math?
Math Formulae. A polygon is a closed plane figure made up of 3 or more line segments. Polygons have special names depending on the number of lines forming their boundary. For example, a polygon with three sides is called a triangle. A polygon with four sides is called a quadrilateral.
