Terminology
- line of symmetry
- axis of symmetry
- mirror line
- reflective symmetry
- regular polygon
Task goals
- Identify and draw the line(s) of symmetry on simple, familiar 2D shapes such as isosceles triangles, rectangles, and letters.
- Determine the exact number of lines of symmetry in regular polygons and everyday figures, and combine this with the shape's order of rotational symmetry.
- Analyse and justify the symmetry properties (lines and rotational order together) of composite, irregular, or real-world designs using correct transformation-geometry language.
