What polygons have 1 interior angle greater than 180?

Polygons with one interior angle greater than 180 degrees are known as non-convex or concave polygons. In these shapes, at least one angle "caves in" towards the interior, causing it to exceed 180 degrees. Examples of such polygons include certain types of concave quadrilaterals and hexagons. In contrast, all angles in convex polygons are less than or equal to 180 degrees.
