Symmetry (reflection)

This CTET Paper 2 chapter builds Symmetry (reflection) for future Classes VI-VIII maths teachers: line of symmetry and mirror line, fold and mirror tests, figures with 0/1/2/many lines, regular polygon n-rule, circle with infinitely many lines, ink-blot and paper-fold TLM, pedagogy of reflection-versus-translation confusion, light Class VII rotational contrast, and hard classroom stems. Construction and full Geometry stay one-line siblings.
