- Regular Polygons can be either convex or concave. A Polygon is termed to be irregular if:All sides are not congruent orAll angles are not congruent orboth the sides are not congruent and the angles are not congruent. Let us look into few examples of irregular polygons.

Nonagon: Definition & Shape Irregular Nonagons. An irregular polygon is a polygon with unequal sides and angles. An irregular nonagon is a nine-sided shape that does not have equal sides or angles. One real world example of an irregular nonagon is the US Steel Building in Pittsburgh, Pennsylvania.It looks like a triangle with each corner indented.efinition. A nonagon is a nine-sided polygon. You may recall that a polygon is a many-sided shape. We use the suffix-gon to indicate the number of sides of a polygon.

Geometric Shapes Polygons. All of these shapes are polygons. A polygon is a shape made of lines that could be colored in (all the lines meet and it has a “middle”). Most of what you will be asked to do with these shapes is recognize them and draw them, so memorize how many sides they have, what they look like, etc.

Basic Geometric Shapes: Square, Circle, Rectangle, and Triangle A polygon is a shape that is closed and is made up of only lines (no curves). It can have no open parts. Polygon in this case is a broader term to encompass a great many shapes including the square, rectangle and triangle. The circle described above cannot be considered a polygon because it is created by using curves, something which is not allowed by the simple definition of a polygon.

- An equilateral pentagon is a polygon with five sides of equal length. However, its five internal angles can take a range of sets of values, thus permitting it to form a family of pentagons. In contrast, the regular pentagon is unique, because it is equilateral and moreover it is equiangular (its five angles are equal).

Polygon In elementary geometry, a polygon /ˈpɒlɪɡɒn/ is a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit. These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices (singular: vertex) or corners. The interior of the polygon is sometimes called its body. An n-gon is a polygon with n sides. A polygon is a 2-dimensional example of the more general polytope in any number of dimensions. The basic geometrical notion of a polygon has been adapted in various ways to suit particular purposes.

polygon polygon. n. 1. (Mathematics) a closed plane figure bounded by three or more straight sides that meet in pairs in the same number of vertices, and do not intersect other than at these vertices. The sum of the interior angles is (n -2) × 180° for n sides; the sum of the exterior angles is 360°.

Dodecagon A polygon is defined as a 2-dimensional shape with straight sides. Regular polygons have sides and angles that are all the same. While you can find the measurements of the exterior and interior angles of regular polygons, you can't with polygons that aren't regular.

- They should also note a pattern between the smallest angle of rotation that carries a regular polygon onto itself and the number of sides of the polygon. Core Standards Focus: G.CO.3 Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.

- A regular polygon is one that has equal sides. Polygons also have diagonals, which are segments that join two vertices and are not sides. The table lists all the polygons having up to 10 sides. Click the name of each polygon in the table to see a diagram.

Types of Polygon Polygons are categorized into different types based on the number of sides as well as the measure of the angles. Most famous polygons are triangles, rectangles, squares, parallelograms, rhombuses, pentagons, hexagons and so on. The pentagon and octagon are demonstrated in the following diagram.

- A regular polygon has 3 or 4 or 5 or more sides and angles, all equal. A regular tessellation means a tessellation made up of congruent regular polygons. [Remember: Regular means that the sides and angles of the polygon are all equivalent (i.e., the polygon is both equiangular and equilateral). Only three regular polygons tessellate in the Euclidean plane: triangles, squares or hexagons.

Convex Polygon A planar polygon is convex if it contains all the line segments connecting any pair of its points. Thus, for example, a regular pentagon is convex (left figure), while an indented pentagon is not (right figure). A planar polygon that is not convex is said to be a concave polygon. Let a simple polygon have vertices for, 2, ..., , and define the edge vectors as. (1). where is understood to be equivalent to. Then the polygon is convex iff all turns from one edge vector to the next have the same sense.

- In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be convex or star.

Icosagon In geometry, an icosagon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees. The regular icosagon is a constructible polygon, by an edge-bisection of a regular decagon, and can be seen as a truncated decagon, t{10}. One interior angle in a regular icosagon is 162°, meaning that one exterior angle would be 18°.

What Shape Has Six Sides? A hexagon is a polygon that can be considered regular or irregular. A hexagon that has six sides that are all the same length is considered a regular hexagon. If the hexagon has sides that vary in length, it is considered an irregular hexagon. Hexagons can also be considered concave or convex.

Polygon Names Play a Rally Game on Polygon Names. In geometry a polygon is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain). These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices or corners.

What is a Polygon? - Definition, Shapes & Angles Definition of a Polygon. A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides. So, any shape that can be drawn by connecting three straight lines is called a triangle, and any shape that can be drawn by connecting four straight lines is called a quadrilateral. All of these shapes are polygons.

Definitions &Translations Polygon. Polygons are used in computer graphics to compose images that are three-dimensional in appearance. Usually triangular, polygons arise when an object's surface is modeled, vertices are selected, and the object is rendered in a wire frame model.
