Attempted by 6 students.
Show answer & explanation
Correct answer: B
A regular polygon with n sides has n lines of symmetry. Therefore, a regular polygon with 10 sides has 10 lines of symmetry. The other statements are false: a regular hexagon has 6 lines of symmetry, a circle has infinitely many lines of symmetry, and an angle has one line of symmetry, its angle bisector.
