The rectangle in figure-1 has 2 lines of symmetry. So it has 2-fold reflection symmetry. The square has 4 lines of symmetry. So it has 4-fold reflection symmetry. Likewise, X and H have 2-fold reflection symmetry, and the club shape has 1-fold reflection symmetry. Also, every regular polygon has reflectional symmetry. Similarly, an equilateral triangle has 2-fold reflection symmetry and an …
