Irregular Polygons: Shapes, Examples, And How To Calculate Perimeter And Area

irregular polygon

A polygon that does not have all sides equal and all angles equal.

An irregular polygon is a closed geometric figure that has sides and angles of different sizes and measures. In other words, it is a polygon that does not have equal side lengths or equal angles. An irregular polygon can have any number of sides and can have a variety of shapes and orientations.

Some examples of irregular polygons include:

1. Pentagon – a five-sided polygon with sides of different lengths.
2. Hexagon – a six-sided polygon with sides that are not equal in length.
3. Octagon – an eight-sided polygon with sides that are not equal in length and angles that are not equal in measure.
4. Concave polygon – a polygon with at least one angle greater than 180 degrees.

To calculate the perimeter and area of an irregular polygon, you need to divide it into smaller geometric shapes such as triangles or rectangles and find their individual perimeters and areas. Once you have found the individual perimeters and areas, you can add them up to find the perimeter and area of the irregular polygon. However, this method can be more complex and time-consuming than finding the perimeter and area of regular polygons.
