Question 9 How many angles of symmetry do the shapes in the first shape sequence in Chapter 1, Table 3, the Regular Polygons, have? What number sequence do you get?The table looks like Regular Polygons – Angles of symmetry Now Regular Triangle (Equilateral Triangle) – 3 angles of symmetry Regular Quadrilateral (Square) – 4 angles of symmetry Regular Pentagon – 5 angles of symmetry Regular Hexagon – 6 angles of symmetry Regular Heptagon – 7 angles of symmetry Regular Octagon – 8 angles of symmetry Regular Nonagon – 9 angles of symmetry Regular Decagon – 10 angles of symmetry The Number sequence we get is 3, 4, 5, 6, 7, 8, 9, 10, …. It is a counting number sequence.
