question 28 of 40
how many lines of symmetry does a regular dodecagon have?
a. 11
b. 10
c. 12
d. 13

Explanation:

Step1: Recall polygon symmetry rule

A regular $n$-sided polygon has $n$ lines of symmetry.

Step2: Identify $n$ for dodecagon

A dodecagon has 12 sides, so $n=12$.

Step3: Apply the rule

Number of lines of symmetry = $n = 12$

Answer:

C. 12
