Not regular quadrilateral

Based on their sides, all quadrilaterals can be broadly classified into two different groups: regular and irregular.

A quadrilateral is a polygon that has exactly four sides. This also means that a quadrilateral has exactly four vertices, and exactly four angles. Discussions of 2-D shapes sometimes refer only to the boundary the line segments that form the edges of the figure or to the interior as well. The usual definitions of polygons, however, refer only to the line segments that form the edges of the polygon. Most of the time, context will make clear what you mean, but you should remain aware that in some cases you may need to clarify.

Based on their sides, all quadrilaterals can be broadly classified into two different groups: regular and irregular. A regular quadrilateral is a type of quadrilateral with four sides of equal length and four angles of equal measure. Example : A square is the only regular quadrilateral. An irregular quadrilateral is a type of quadrilateral having one or more sides of unequal length and one or more angles of unequal measure. Examples : Rectangle , parallelogram , rhombus , trapezoid , and kite are irregular quadrilaterals. A square is the only regular quadrilateral known to us. Thus, to find the area of a regular quadrilateral we will use the formula for determining the area of a square.

A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles. There are two main types: concave and convex. There are also various subcategories of convex quadrilaterals, such as trapezoids, parallelograms, rectangles, rhombi, and squares.
