Educational video for children to learn what polygons are and how we classify them. A polygon is a plane figure described by a closed, polygonal line. Polygons are formed by several parts: sides, vertices, angles and diagonals. Also, they can be regular (all sides and angles equal) or irregular (not all sides or angles equal). Polygons are classified according to the number of sides in triangles, quadrilaterals, pentagons, etc. This video features several examples of objects around us.
