Wielokąty - Matematyka Szkoła Podstawowa i Gimnazjum

In this video, I introduce what polygons are, teach you how to recognize geometric figures composed solely of line segments, show the differences between polygons and other figures that contain arcs or curves, explain the concepts of vertices, sides, and angles of a polygon and their interrelationships, demonstrate the naming of polygons based on the number of angles, discuss how to name polygons by listing vertices, and show which points belong to a polygon, including both the points on the edges and the points inside the figure. Table of Contents: 1. Definition of a Polygon 2. Recognizing Polygons Among Figures 3. A Polygon as a Closed Polygon 4. Examples of Polygons and Non-Polygons 5. Vertices, Sides, and Angles of a Polygon 6. Relationship between the Number of Sides, Vertices, and Angles 7. Naming Polygons by Angle 8. Triangles, Quadrilaterals, Pentagons, Hexagons, Heptagons 9. Names of Polygons with Labeled Vertices 10. Points Belonging to a Polygon – Edges and Interior The end of this video:    • Dokończenie filmu p.t. Wielokąty   You can find more in the Playlist:    • GEOMETRIA NA PŁASZCZYŹNIE   Get EASY ACCESS to all my math lessons using my Website: www.matmagwiazdy.pl On this channel, you will find a full lecture - 100% of the lesson - on Mathematics for Elementary School, High School, and Technical School.
