A regular pentagon has how many lines of symmetry?

A. 3B. 4C. 5D. 6

To solve this question, let's consider the properties of a regular pentagon:

A regular pentagon is a five-sided polygon where all sides and angles are equal. The lines of symmetry in a shape are the lines where you can fold the shape such that both halves match perfectly.

For a regular pentagon:

It has 5 sides and 5 angles that are congruent.
The lines of symmetry are the lines that can divide the pentagon into two identical halves.
In a regular pentagon, each line of symmetry passes through one vertex and the midpoint of the opposite side.
Since a regular pentagon has 5 vertices, and each vertex can have a line of symmetry passing through it, there are 5 lines of symmetry.

Thus, the correct answer is:

C. 5
