## What is a 4 sided shape with unequal sides?

A quadrilateral with 4 unequal sides could be a convex or a concave quadrilateral whose 4 angles and 4 sides do not match any of the others. … (e) Lines joining the mid points of the sides of a quadrilateral in an order form a parallelogram.

## What is a polygon with 4 sides that are different lengths?

Quadrilaterals are polygons with four sides (hence the beginning “quad”, which means “four”). A polygon with non-equal sides is called irregular, so the figure that you are describing is an irregular quadrilateral. This figure has side lengths of 1, 2, 3, and 4 respectively, so it is an irregular quadrilateral.
