A regular polygon is a polygon in which all sides are equal and all angles are equal, Examples of a regular polygon are the equilateral triangle (3 sides), the square (4 sides), the regular pentagon (5 sides), and the regular hexagon (6 sides).

What is a regular polygon short definition?

A polygon is called regular if it has equal sides and angles. Thus, a regular triangle is an equilateral triangle, and a regular quadrilateral is a square.

Does a regular polygon have 3 sides?

A regular polygon having 3 sides is known as an equilateral triangle.

What is polygon regular polygon?

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 either convex or star.

What is regular polygon with examples?

A regular polygon is a polygon with congruent sides and equal angles. The examples of regular polygons include equilateral triangle, square, regular pentagon, and so on.

What is a polygon with 4 sides?

Definition: A quadrilateral is a polygon with 4 sides. Definition: A parallelogram is a quadrilateral where both pairs of opposite sides are parallel.

What is a regular polygon definition for Class 8?

A polygon having equal sides of equal lengths are called regular polygons. A regular polygon is a polygon that is equiangular i.e. All the angles are equal in measure and equilateral i.e. all sides have the same length.

What is the definition of regular polygon and irregular polygon?

A polygon which has all its sides of equal length and all its angles of equal measures is called a regular polygon. A polygon which has all its sides of unequal length and all its angles of unequal measures is called an irregular polygon.

What polygon has 4 sides?

Definition: A quadrilateral is a polygon with 4 sides. A diagonal of a quadrilat- eral is a line segment whose end-points are opposite vertices of the quadrilateral.

What is regular and irregular polygons?

Regular polygon: A polygon which has all its sides of equal length and all its angles of equal measures is called a regular polygon. A polygon which has all its sides of unequal length and all its angles of unequal measures is called an irregular polygon.

How many sides does a regular polygon have?

A regular polygon has: Two dimensions Straight sides Congruent (equal-length) sides An interior and exterior Equal interior angles Equal exterior angles

Can regular polygon have equal sides and equal angles?

A regular polygon is a two-dimensional shape having all sides of equal length and all interior angles of equal measure . Thus sides and angles are the two parts of a regular polygon that are always congruent. They are thus both equilateral and equiangular.

How do you tell if a polygon is a regular polygon?

A regular polygon is equilateral (it has equal sides) and equiangular (it has equal angles). To find the area of a regular polygon, you use an apothem — a segment that joins the polygon’s center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).

What is the difference between a regular polygon and Polygon?

A regular polygon is one where all the sides are congruent and all the interior angles are congruent. Regular polygons. An irregular polygon is one that is not regular.
