An irregular polygon, also known as non-regular polygon is a shape that does not have all sides of equal length and all angles of equal measure. Thus any polygon that is not regular is an irregular polygon. Examples. A scalene triangle, rectangle, trapezoid or a kite are common examples of irregular polygons.
In geometry, regular and irregular polygons are also called regular and irregular shapes. These are the types of polygons that differ from each other with respect to their dimensions. The polygon is a two-dimensional closed shape with all its sides connected to each other. The point at which two sides meet is called the vertex.
Regular or Irregular. A regular polygon has all angles equal and all sides equal, otherwise it is irregular : Regular : Irregular . Concave or Convex.
Here are some examples of irregular polygons. Figure 5.20.4 5.20. 4. In these polygons, some sides are clearly longer than others and some angles are wider than others, so they must be irregular. Notice that irregular polygons tend to look uneven or lopsided, while regular polygons look more orderly and symmetrical.
In other words, irregular polygons are not regular. Polygons are closed two-dimensional figures that are formed by joining three or more line segments with each other. There are two types of polygons, regular and irregular polygons. Let us learn more about irregular polygons, the types of irregular polygons, and solve a few examples for better ...
A regular (or simple) polygon is a shape with equal angles and multiple sides with equal lengths. Regular polygons can also be categorized as convex polygons because the equal sides canter inward where they connect, creating several v-shaped vertices. 2. Irregular Polygon. An irregular (or complex) polygon has at least one interior angle that ...
The area of a polygon is defined as the measurement of space enclosed within a polygon. The area of polygons can be found by different formulas depending upon whether the polygon is a regular or an irregular polygon. For example, a triangle is a three-sided polygon which is known as a trigon.
Solution: Regular Polygons: Reason: Fig (a), All the sides in the given polygon are equal. Hence, it is a regular polygon. Reason: Fig (b), The given octagon is a regular polygon as all the angles in it are equal. Irregular Polygons: Reason: Fig (d), Here, the polygon is irregular as it has unequal angles.
Example 1: classify the shape by sides and regular or irregular. Name the type of polygon. State the number of sides. The polygon has 6 sides. 2 Recall the definition. A regular polygon has sides that are the same length and angles that are the same size. An irregular polygon has sides that are not the same length and angles that are the same size.
Polygons are two-dimensional geometric objects composed of points and straight lines connected together to close and form a single shape. Irregular polygons are polygons that have unequal angles and unequal sides, as opposed to regular polygons which are polygons that have equal sides and equal angles. As the concept of irregular polygons is extremely general, knowledge about this concept can ...
Irregular polygons generally don’t have equal sides. Rhombus is an example of an irregular polygon; it has equal sides, but unequal angles. Regular polygons have equal interior/exterior angles. In irregular polygons, the measure of all interior/ exterior angles is not equal. A rectangle is an example of an irregular polygon where all the ...
Then, label the polygon as regular or irregular. Irregular. The answer is that the polygon is an irregular hexagon. Example 2. Name this figure. First, count the number of sides. The shape has 5 sides. Next, determine if the sides are congruent. The sides are not congruent. Then, label the polygon as regular or irregular. Irregular.

We can learn a lot about regular polygons by breaking them into triangles like this: Notice that: the "base" of the triangle is one side of the polygon. the "height" of the triangle is the "Apothem" of the polygon. Now, the area of a triangle is half of the base times height, so: Area of one triangle = base × height / 2 = side × apothem / 2.
A polygon which has all its sides of unequal length and all its angles of unequal measures is called an irregular polygon or non-regular polygons. Definition of Irregular Polygons: A polygons is called a non-regular or irregular polygon, if all the sides are not equal. The following figures are irregular polygons.
Example 1: classify the shape – by sides and regular or irregular. Name the shape. Check to see that the polygon has different size angles or sides. There are sides and angles that are not congruent (equal), so the polygon is irregular. 2 Count the number of sides of the polygon.
Irregular polygons These are shapes that have sides and angles of different sizes . You can always identify the polygon by how many sides it has, eg. a pentagon is always a shape that has 5 sides.
Therefore, a regular pentagon is a regular polygon. Irregular Polygon – Definition. A polygon that consists of unequal sides with unequal lengths and also having unequal angles called an irregular polygon. Examples of Irregular Polygon. Let us have a look at the different Examples of a Regular Polygon below. Scalene Triangle:
Identify the number of sides and whether any polygons are regular/irregular. This polygon has four sides. This polygon is irregular as all the sides are not of equal length. 2 Find the sum of interior angles of the polygon(s). Sum of interior angles =(n-2)\times{180} As the polygon has 4 sides, n=4, so you can substitute n=4 into the formula.
Regular or irregular polygons are also possible. Regular polygons must be examined first in order to define an irregular polygon. A regular polygon is one that has the same length on all sides and the same number of interior angles. A three-sided regular polygon, for example, is a yield street sign. What are regular and irregular polygons give ...
