1. a. Letters with a vertical axis of symmetry are M A T and H
b. The only letter with a horizontal axis of symmetry is H
2. Letters with rotational symmetry of order 2 are H and S
Note that 3 c. is not a REGULAR hexagon and that parallelograms (3 d.) have NO axes of symmetry.
5. Possible answers are:
6. a. False. An equilateral triangle has 3 axes of symmetry.
