Study Notes
- Polygons are multi-sided shapes with sides, vertices, and angles, and they are 2-dimensional or flat shapes.
- For a shape to be considered a polygon, it must be closed, meaning that the sides are connected with no gaps.
- Examples of polygons include squares, stars, and pentagons, while shapes like circles and 3D objects are not polygons.
- Special names are given to polygons based on the number of sides they have: triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), hexagons (6 sides), and octagons (8 sides).
- Regular polygons have equal angles, while irregular polygons have unequal angles.
- Understanding polygons and their properties is essential in geometry, and they play a crucial role in various mathematical concepts.
- By identifying the characteristics of polygons, individuals can distinguish between polygons and non-polygons in different shapes and figures.
