Study Notes
Reflectional Symmetry
- A regular hexagon possesses 6 lines of reflectional symmetry.
- An isosceles trapezoid has 1 line of reflectional symmetry that is vertical.
- The trapezoid exhibits rotational symmetry of order 1.
Rotational Symmetry
- The smallest angle of rotational symmetry for a regular octagon is 45°.
- A parallelogram has 2 as its order of rotational symmetry.
- Regular nonagons show rotational symmetry at the angles of 40°, 120°, 240°, and 320°.
- A regular polygon with a smallest rotational symmetry angle of 30° has 12 sides.
Polygon Specifics
- A square maintains 4-fold reflectional symmetry and has an order of 4 rotational symmetry.
- In a regular decagon, rotating counterclockwise by 3 times the smallest angle of rotation will place vertex E at the top.
Diagram Representations
- Diagrams are used to illustrate lines of symmetry for regular polygons, including the correct diagram for the regular pentagon being indicated as B for accuracy.
- Another diagram labeled as B represents the line of symmetry for the regular octagon.
