## What is an irregular 2D shape?

Irregular shapes are shapes of which the sides and interior angles are not all the same.

## What are regular and irregular shapes with examples?

The definition of a regular shape is that all the sides are equal and all the inside angles are equal. An irregular shape doesn’t have equal sides or equal angles. For example, an equilateral triangle is a regular shape because all the sides are equal AND all the angles are equal.

**What are regular and irregular shapes objects?**

A regular shape is a shape, which has equal angles and equal sides – its sides are all the same length. On the other hand, an irregular shape has sides of different lengths and angles of different sizes.

### What’s an irregular shape?

Irregular shapes are polygons with five or more sides of varying lengths. These shapes or figures can be decomposed further into triangles, squares, and quadrilaterals to evaluate the area. Some examples of irregular shapes are as follows: Daily life objects with irregular shapes.

### What is regular object?

Those substances that have fixed geometrical shapes are called regular objects. Some of the examples of regular objects are books, pencils, chalk box, basketball, etc. Those substances which do not have a fixed geometrical shape are called irregular objects.

**What is an irregular shape?**

An irregular shape is one where the sides and angles can be different sizes. The two shapes below are both pentagons (they have 5 sides). The orange one is a regular pentagon, whereas the blue one is an irregular one.

## What is the difference between a regular and irregular polygon?

A Regular polygon is a shape with straight sides. If all the sides are the same length, the shape is regular. Regular shapes have equal angles and equal sides. Examples include a regular triangle and a square. An irregular polygon is a shape with straight sides, but if any of these are of different lengths, the shape is irregular.

## What is the 2D and 3D shapes bundle?

This bundle has over 100 engaging slides which allows students to compose and decompose 2D and 3D shapes. 2D shapes are circles, triangles, Subjects:

**How can I help my child learn about regular and irregular polygons?**

Children can draw their own pictures of regular and irregular polygons, before arranging around each poster. In doing so, they can appreciate their hard-work when seeing it on show. To help children in future lessons, you could print these posters onto a smaller size, before sticking into exercise books.
