o What is a polygon? (answer: it is a flat, 2- dimensional closed geometric shape bounded by 3 or more straight line segments (called sides), and an equal number of points (called vertices) --- note: a circle is not a polygon because it does not have straight sides). o A vertex (plural “vertices”) is a corner. A side joins one vertex with ...
a polygon is what we call a global property. The opposite is a local property. The size of an angle is a local property. You only need to glimpse a tiny neighbourhood around the vertex of the angle to decide the size of the angle. Property no. 2 for polygons: Size and shape (as long as they are polygons) are irrelevant.
Polygons are just any closed shape with straight lines which don’t cross. Like a square or triangle. All polygons need at least three sides to form a closed path.
Geometric shapes such as a square, rectangles, and triangles are a few basic 2D shapes. These figures are collectively called polygons. A polygon is any flat shape or plane on a surface of a paper.

In geometry, the definition of a polygonis given as a closed two-dimensional figure which is formed by three or more straight lines. The properties of polygons help us identify them easily. In other words, the following characteristics of a polygon help us to easily check whether a given shape is a polygon or not 1. A polygon is a closed shape, tha...
The sides of a polygon define the name of the specific polygon because different polygons have different number of sides. For example, if a polygon has 3 sides, then it is called a triangle, whereas, if a polygon has 4 sides, it is a quadrilateral. The following section shows the different types of polygons along with their names based on the numbe...
There are different types of polygons and they have different names depending on the number of sides that they have. For example, a 3-sided polygon is a triangle, a 4-sided polygon is a quadrilateral, a 5-sided polygon is a pentagon, a 6-sided polygon is a hexagon, and so on.
The following chart shows the naming convention of polygons on the basis of the number of sides that they have. Each polygon is given a special name on the basis of its number of sides. For example, the trigon, also known as the triangle is made of two words 'tri' which means three, and 'gon' means angles. This shows that it is a shape that has thr...
It is said that as per Euclidean Geometry, a polygon that is equiangular and equilateral is called a regular polygon while a polygon whose sides are not equiangular and equilateral is referred to as an irregular polygon. Regular polygons are always convex,i.e., all the interior angles measure less than 180º. In simple words, a regular polygon has a...
The interior angles are formed between the adjacent sides inside the polygon and are equal to each other in the case of a regular polygon. The number of interior anglesis equal to the number of sides. The value of an interior angle of a regular polygon can be calculated if the number of sides of the regular polygon is known by using the following f...
Each exterior angle of a regular polygon is formed by extending one side of the polygon (either clockwise or anticlockwise) and then the angle between that extension and the adjacent side is measured. Each exterior angle of a regular polygonis equal and the sum of the exterior angles of a polygon is 360°. An exterior angle can be calculated if the ...
The area of a polygon is defined as the measurement of space enclosed within a polygon. The area of polygons can be found by different formulas depending upon whether the polygon is a regular or an irregular polygon. For example, a triangle is a three-sided polygon which is known as a trigon. The formula for calculating the area of the trigon (tria...
The perimeter of a polygon is defined as the distance around a polygon which can be obtained by summing up the length of all given sides. The perimeter of polygon formula = Length of Side 1 + Length of Side 2 + Length of Side 3...+ Length of side N (for an N-sided polygon). It is expressed in terms of units such as meters, cm, feet, etc. Concave po...
The polygons worksheets helps children recognize more shapes and patterns in real life. It also develops the base of understanding and establishing the necessary basic background for geometry.
edge or side. Polygons contain two main types of angles, interior angles and. exterior angles. Shown below is a regular pentagon. Its interior angles are displayed in red and its exterior angles are in green. The definition of an exterior angle is the angle you have to turn through in to change your direction from one side to that of the next side.
