Among plane figures, it is important to distinguish between polygons and non-polygons. A polygon is a closed plane figure that is formed by line segments joined end-to-end . Non-polygons define the set of plane figures which have curved lines or which include unclosed lines.

In geometry, a polygon can be defined as a flat or plane, two-dimensional closed shape bounded with straight sides. It does not have curved sides. The sides of a polygon are also called its edges. The points where two sides meet are the vertices (or corners) of a polygon. Here are a few examples of polygons. Here are a few non-examples of a polygon
Polygons are named on the basis of the number of sides it has. Polygons are generally denoted by n-gon where n represents the number of sides it has, For example, a five-sided polygon is named as 5-gon, a ten-sided is named as 10-gon, and so on. However, few polygons have some special names. The minimum number of sides a polygon can have is 3 becau...
The polygons can be classified on the basis of the number of sides and angles it has: 1. Classification on the basis of sides: Regular and Irregular Polygons: Regular Polygons– Polygons that have equal sides and angles are regular polygons. For example, an equilateral triangle is a three-sided regular polygon. A square is a four-sided regular polyg...
Example 1: Fill in the blank. 1. The name of the three sided regular polygon is ________________. 2. A regular polygon is a polygon whose all _____________ are equal and all angles are equal. 3. The sum of the exterior angles of a polygon is __________. 4. A polygon is a simple closed figure formed by only _______________. Solution: 1. equilateral ...
Here we shall discuss a few fundamental elements of plane geometry – curve, angle and polygon. A curve is a smoothly flowing line that you can draw on a paper without using a ruler. The random lines that you doodle on paper are also curves. There are three types of the curve: Simple curves: Curve that does not intersect itself at any point.
Nov 29, 2018 · A simple closed curve or a polygon formed by three line-segments (sides) is called a triangle. The above shown shapes are triangles. The symbol of a triangle is ∆.
Jun 30, 2024 · Curve is a plane figure which is made by joining a number of points without lifting a pencil from paper and without retracing any portion of drawing. Moreover, a curve which does not intersect itself is called open curve and on the other hand, a curve which intersect itself is called closed curve.
- A closed plane figure formed by line segments and two line segments which intersect at only their end points.
- The sum of angles of polygon with n sides is (n-2)180 0 .
- Sum of exterior angles of polygon is 360 0 .
- Yes, equilateral triangle is a regular polygon as its all sides are equal and all its angles are equal.
- No, rectangle is not a regular polygon as its angles are equal but all sides are not equal.
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up). Polygon comes from Greek. Poly- means "many" and -gon means "angle". A regular polygon has all angles equal and all sides equal, otherwise it is irregular. A convex polygon has no angles pointing inwards.
