Line Symmetry
A figure has line symmetry if a line divides it into two parts that are mirror images. That line is the line of symmetry. A regular polygon of n sides has n lines of symmetry; a circle has infinitely many. An isosceles triangle has 1, a rectangle 2, a rhombus 2, a kite 1 and a parallelogram 0.
Rotational Symmetry
A figure has rotational symmetry if it looks the same after a turn of less than 360° about a fixed point (the centre). The number of times it looks the same in one full turn is its order, and the smallest angle of such a turn is 360° divided by the order. A square has order 4, a rectangle and a parallelogram 2, an equilateral triangle 3.
Reflection
The reflection of a figure in a mirror line reverses left and right. Letters such as A, H, M, T have vertical lines of symmetry; B, C, D, E have horizontal lines; H, I, O, X have both; and F, G, J, P, Q, R have none.
Worked Example
A regular hexagon has 6 lines of symmetry and rotational symmetry of order 6, with angle of rotation 360° / 6 = 60°.
