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.

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: 1. Simple curves: Curve that does not intersect itself at any point. In the figure, (i), (iii), (iv) and (vii) are simple curves. 2. Open curves: Curve whose end points...
An angle is an inclination of two rays that emerges from a common point. This point is called the vertex of the angle and the two rays forming the angle are called its arms or sides. Note: 1. If the arms form an angle of 90 degrees between them, it is called a right angle. 2. If the inclination between the arms is less than a right angle, it is cal...
A polygon is a flat figure enclosed by three or more line segments. The line segments are called the sides of the polygon. The point where two line segments meet is called the vertex of the polygon. The pair of sides that meet at the same vertex are called adjacent sides. The endpoints of the same side are called the adjacent vertices. The line seg...
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
- A diagonal of a polygon is a line segment connecting two non-consecutive vertices (corners).
- A Regular polygon has all sides of equal length and each angle also measures equal.
- Polygon is a closed shape made up of straight-line segments. The circle is a closed figure but it is made of a curve. So, a circle is not a polygon.
- A polygon must have a minimum of three sides.
- No, polygons have the same number of sides and angles because they are closed figures with non-intersecting lines.
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.
Jan 2, 2022 · Polygons must have at least three sides, thus the polygons with the fewest number of sides are triangles. Circles and semicircles are not polygons because they have curved sides. When all the sides of a polygon are equal, it is equilateral (ee-quee-LAH-teh-roll). When all the angles of a polygon are equal, it is equiangular (ee-quee-ANG-ger-lah).
