Explanation:</h2><h2 />
Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume you want an explanation for polygons, quadrilaterals and parallelograms. So let's get started:
1. Polygon: A <em>polygon </em>is any flat shape that is closed and has straight lines as its sides.
2. Quadrilateral: A <em>quadrilateral </em>is a polygon that has four sides. Those sides can be either equal or not.
3. Parallelogram: A <em>parallelogram </em>is a polygon and also a quadrilateral because it has four sides such that the opposite sides are parallel and equal in length.
<u>In conclusion:</u>
- A parallelogram is both a polygon and a quadrilateral
- A quadrilateral is a polygon
