               HOME ASSIGNMENT:

               1. State the number of lines of symmetry for the following figures: (a) An equilateral
               triangle (b) An isosceles triangle (c) A scalene triangle (d) A square (e) A rectangle
               (f) A rhombus (g) A parallelogram (h) A quadrilateral (i) A regular hexagon (j) A
               circle.

               2. What letters of the English alphabet have reflectional symmetry (i.e., symmetry
               related to mirror reflection) about  (a) a vertical mirror (b) a horizontal mirror (c) both
               horizontal and vertical mirrors.


               3. Give three examples of shapes with no line of symmetry.

               4. What other name can you give to the line of symmetry of (a) an isosceles triangle?
               (b) a circle?
