Different Types of Polygons

A polygon is a plane figure that is made by joining the line segments, where each line segment meets exactly two other line segments. The intersection point of two line segments is called the vertex of the polygon.

Polygons are of two types:
(i) Regular polygon
(ii) Irregular polygon

Regular and irregular polygon

If all the sides and angles of a polygon are equal, then the polygon is called a regular polygon, otherwise it is called an irregular polygon. Equilateral triangle and square are examples of regular polygon because in equilateral triangle and square, all the sides and all the angles are equal. A triangle in which all the sides are different is called an irregular polygon. Scalene triangle, isosceles triangle, rectangle, etc. are irregular polygons.

Polygon

A polygon is a closed figure that is the union of line segments in a plane. A polygon has three or more sides.
A polygon has the same number of angles as sides.

Polygons 1

Polygons can be classified as either convex or concave.

A polygon is convex if no line that contains a side of the polygon contains a point in the interior of the polygon. In a convex polygon, each interior angle measures less than 180 degrees.
Concave polygons “cave-in” to their interiors, creating at least one interior angle greater than 180 degrees (a reflex angle).

Do not assume that the diagrams under the “Graphic” column are “regular” polygons. Do not assume any specific details about the diagrams such as the length of the sides or measures of the angles.
Polygons 4

A polygon is equilateral if all of its sides are of the same length.
A polygon is equiangular if all of its angles are of equal measure.

A regular polygon is a polygon that is both equilateral and equiangular.
