What are irregular polygons?

[smithudee]

I’m learning about different types of polygons. Can someone explain irregular polygons and how they differ from regular polygons?

Irregular polygons are polygons whose sides and angles are not all equal, unlike regular polygons which have equal sides and angles.

An irregular polygon is a polygon whose sides and angles are not all equal. Unlike regular polygons, which have congruent sides and angles, irregular polygons vary in length and measure. Examples include scalene triangles, rectangles, or any many-sided shape without uniform sides or angles.
