Definition: What are Irregular Shapes? 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.

A scalene triangleis considered an irregular polygon, as the three sides are not of equal length and all the three internal angles are also not in equal measure and the sum is equal to 180°. In the triangle PQR, the sides PQ, QR, and RP are not equal to each other i.e. PQ ≠ QR ≠ RP. Also, angles ∠P, ∠Q, and ∠R, are not equal, ∠P ≠ ∠Q ≠ ∠R. Thus, we...
An isosceles triangleis considered to be irregular since all three sides are not equal but only 2 sides are equal. All three angles are not equal but the angles opposite to equal sides are equal to measure and the sum of the internal angles is 180°. In the triangle, ABC, AB = AC, and ∠B = ∠C. All the three sides and three angles are not equal.
A rectangleis considered an irregular polygon since only its opposite sides are equal in equal and all the internal angles are equal to 90°. In the given rectangle ABCD, the sides AB and CD are equal, and BC and AD are equal, AB = CD & BC = AD. And, ∠A = ∠B = ∠C = ∠D = 90 degrees. But, AB ≠ AD or BC BC ≠ AB or CD CD ≠ AD or BC AD ≠ AB or CD Hence, ...
A right triangleis considered an irregular polygon as it has one angle equal to 90° and the side opposite to the angle is always the longest side. Therefore, the lengths of all three sides are not equal and the three angles are not of the same measure. In the right triangle ABC, the sides AB, BC, and AC are not equal to each other. AB = BC = AC, wh...
A pentagonis considered to be irregular when all five sides are not equal in length. However, sometimes two or three sides of a pentagon might have equal sides but it is still considered as irregular.
A hexagonis considered to be irregular when the six sides of the hexagons are not in equal length. The measurement of each of the internal angles is not equal. By the below figure of hexagon ABCDEF, the opposite sides are equal but not all the sides AB, BC, CD, DE, EF, and AF are equal to each other. Since the sides are not equal thus, the angles w...
An irregular polygon is a plane closed shape that does not have equal sides and equal angles. Thus, in order to calculate the area of irregular polygons, we split the irregular polygon into a set of regular polygons such that the formulas for their areasare known. Consider the example given below. The polygon ABCD is an irregular polygon. Thus, we ...
Polygons that do not have equal sides and equal angles are referred to as irregular polygons. Thus, in order to calculate the perimeterof irregular polygons, we add the lengths of all sides of the polygon. Example:Find the perimeter of the given polygon. Solution:As we can see, the given polygon is an irregular polygon as the length of each side is...
Theinterior anglesof a polygon are those angles that lie inside the polygon. Observe the interior angles A, B, and C in the following triangle. The interior angles in an irregular polygon are not equal to each other. Therefore, to find the sum of the interior angles of an irregular polygon, we use the formula the same formula as used for regular po...
An exterior angle (outside angle) of any shape is the angle formed by one side and the extension of the adjacent side of that polygon. Observe the exterior angles shown in the following polygon. To calculate the exterior angles of an irregular polygon we use similar steps and formulas as for regular polygons. The sum of the exterior angles of a pol...
Irregular shapes are shapes where 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 when they are initially introduced to shapes.

Common examples of irregular polygons are a scalene triangle, kite, rectangle. The image below shows the difference between a regular hexagon and an irregular hexagon. Irregular Polygons: Definition.
Irregular shapes are not so simple; their sides and angles are not the same size. Some examples of irregular shapes are irregular pentagons, right-angled triangles and irregular hexagons.
A regular shape is a two-dimensional (2D) shape whose (interior) angles and sides all have the same measurements, while an irregular shape is a shape with sides and angles of any length and measurement.
