Worked Solution

Step 1: A regular hexagon has 6 equal sides and 6 equal angles. Step 2: For any regular polygon with n sides, the number of lines of symmetry equals n. Step 3: Therefore a regular hexagon has 6 lines of symmetry. Step 4: To verify: there are 3 lines through pairs of opposite vertices AND 3 lines through midpoints of pairs of opposite sides. 3 + 3 = 6. Answer: 6.

Correct answer: 6
