An irregular shape is a form that does not have a consistent or uniform outline. Unlike regular shapes, such as circle, square, or triangle, which have defined measurements and angles, irregular shapes can vary widely in size and structure. They often appear in nature, like the shape of a cloud or a rock, where the edges and angles are unpredictable. These shapes can be described using various characteristics, such as the number of sides or the overall area they occupy. Irregular shapes are important in fields like art, architecture, and mathematics, where they can be used to create unique designs or solve complex problems.
