It's an irregular polygon
Quadrilateral is a mathematical term used for any figure with its area bounded by four straight line segments forming a closed path.
All polygon sides are segments of lines.
A closed, convex, plane (2-dimensional) shape.
Draw two line segments at a right angle, and add three more line segments to complete a closed figure.
They are closed plane figures bounded by straight lines.
They are polygons which have 3 or more line segments
polygons
If the line segments are straight, then it is a triangle.
A polygon
Any two-dimensional, closed figure that is not made up entirely of line segments is not a polygon. Examples would include:circleclosed semi-circleellipse
a closed figure with all straight line segments is called a polygon.
Any closed figure formed by a set of straight linesegments is a polygon. If the segments are curved such as in a circle or oval, the closed figure is not a polygon.
A polygon is a closed, 2-dimensional (planar) shape made up of three or more straight line segments connected end to end to end.By this definition, triangles, quadrilaterals and pentagons are all examples of polygons. Circles (etc.) are not, as they are not composed of (straight) line segments. Note that the shape can be convex (which we're used to) or concave, meaning that all the straight line segments may not lie along a "perimeter" but can "go inside" and "come back out" to form the shape.A plane figure with at least three straight sides and angles, and typically five or more.
A polygon is a plane figure that is closed with straight line segments.

A plane shape. There is no specia name unless all the line segments are straight.
A polygon is a closed 2-D shape with sides made from straight line segments.
