Yes, but only if they are straight line segments. And, in that case, the shape is a quadrilateral.
A irregular is a closed plane figure formed by three or more line segments.
A closed plane figure formed by three or more line segments that do not cross is called a polygon. The line segments are known as the sides of the polygon, and the points where the sides meet are called vertices. Common examples of polygons include triangles, quadrilaterals, pentagons, and hexagons. Polygons can be classified as regular, with equal sides and angles, or irregular, with varying lengths and angles.
