Chapter 10 Geometric Figures
§ 10.2 Polygons and Tessellations
- Angles in Polygons
- Congruence
- Congruent line segments
- Congruent angles
- Congruent plane figures
- Regular Polygons
- Equilteral Triangle
- Square
- Others
- Polygon Angles
- Internal, aka vertex
- External
- Central
- Drawing Regular Polygons
- Method 1: Line segments and angles repeated
- Method 2: Inscribe in circle from central angle
- Try on paper if a protractor is available
- Try in Geogebra, geometry version
or maybe Geogebra, classic version
- Tesselations
