# What properties of a polygon make it regular?

A polygon can be regular or irregular. A regular polygon has all sides of equal length, and all angles of equal size. An irregular polygon has sides of different lengths and angles of different sizes.

## Given this, what makes a polygon regular?

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.

## Accordingly, the question is what makes a polygon irregular or regular?

A polygon that does not have all sides equal and all angles equal. (A polygon is "regular" only when all angles are equal and all sides are equal, otherwise it is irregular.)

## Accordingly, we may wonder how do you know if a polygon is regular?

A polygon is regular when all angles are equal and all sides are equal (otherwise it is "irregular").

#### What are the 3 characteristics of a polygon?

What are the 3 characteristics of a polygon
• Answer: The number of sides of the shape.
• The angles between the sides of the shape.
• The length of the sides of the shape.
• Step-by-step explanation:

#### What are the examples of irregular polygon?

Any polygon that does not have all congruent sides is an irregular polygon. Irregular polygons can still be pentagons, hexagons and nonagons, but they do not have congruent angles or equal sides.

#### What is the definition of irregular polygon?

That is, an irregular polygon is a polygon that does not have all sides of equal lengths and all interior angles equal. For example, consider this picture of an SD card: 5-sided Irregular Polygon. Notice the SD card has 5 sides and they are not all equal length. Also, the interior angles are not all equal.

#### How many sides has a regular polygon?

Each interior angle is 165°. Therefore, the number of sides of the regular polygon is 24.

#### Are all closed shapes polygons?

Polygons. A polygon is any closed, 2-dimensional figure that is made entirely of line segments that intersect at their endpoints. Polygons can have any number of sides and angles, but the sides can never be curved.

#### What is irregular shapes in art?

Irregular shapes are shapes of which the sides and interior angles are not all the same. They can be harder for children to identify as they don't look like the conventional shape they are used to seeing. The only regular quadrilateral is a square because all of its sides and angles are of equal length.

#### How many sides does a polygon have with an interior angle of 160?

If the interior angle of a regular polygon is 160 degrees, then the exterior angle is 20 degrees. The sum of all exterior angles is 360 degrees so there must be 360/20 sides = 18 sides.

#### What is not a polygon shape?

The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon. A shape that is not fully closed is not a polygon.

#### What polygon will always be irregular?

Any polygon that does not have all congruent sides is an irregular polygon. Irregular polygons can still be pentagons, hexagons and nonagons, but they do not have congruent angles or equal sides. Here are some examples of irregular polygons.

#### What is an example of an irregular polygon?

A polygon which has all its sides of unequal length and all its angles of unequal measures is called an irregular polygon. Examples of irregular polygon: So, all the angles are not equal to each other. Therefore, a square is an irregular polygon.

#### What is an irregular Heptagon?

A heptagon is a seven-sided polygon. Along with seven sides, a heptagon has seven vertices and angles. A regular heptagon is a heptagon that has congruent sides and angles. An irregular heptagon is any heptagon with sides and angles that are not all congruent.

#### What is a shape that is not a polygon?

Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons - a polygon, by definition, is made up of straight lines. See our pages on circles and curved shapes for more.

#### What do you call the four sided polygon?

Definition: A quadrilateral is a polygon with 4 sides. We name a quadrilateral by naming the four vertices in consecutive order. So we can name the quadrilateral as ABCD, or quadrilateral BCDA, or ADCB. Definition: A Trapezoid is a quadrilateral with a pair of parallel sides.

#### Is Circle an irregular shape?

Is a circle a regular shape or an irregular shape? So yes, a circle is about as regular as a shape can be. You can define a circle with just a center and a radius. Compare this, for example, to the shape of a human body, which would be rather irregular, requiring a lot of information to describe it fully.

#### What shape is an irregular polygon?

Any polygon that does not have all congruent sides is an irregular polygon. Irregular polygons can still be pentagons, hexagons and nonagons, but they do not have congruent angles or equal sides.

#### What do you call a polygon with 3 sides?

A polygon with three sides is a triangle.

#### How can you tell if its a polygon?

Definition of a Polygon A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.

#### What kind of shape is called irregular shape?

An irregular shape is a shape which has sides and angles of any length and size.

#### What are the examples of irregular shape?

Examples of Irregular Shapes
Shape NameProperties
Rectangle4 equal angles; Although the opposite sides are equal, the adjacent sides are not.
KiteUnequal angles Although 2 pairs of sides are equal, not all 4 are equal.
Irregular quadrilateral (more examples)Not all 4 angles are equal; Not all 4 sides are equal

#### Do all regular polygons equiangular?

Regular polygons are both equiangular and equilateral, so all angles in it are congruent and all sides are congruent.

#### Is a circle an irregular polygon?

Polygons. A polygon is a closed plane figure with three or more sides that are all straight. A circle is not a polygon as it does not have straight sides.
