Question

How many lines of symmetry does a regular pentagon have?

Answer 1

Estimate the lines of symmetry:

1. The line of symmetry is the imaginary axis passing through the center of the object.
2. It divides the object into two equal halves.
3. A pentagon is a polygon that has $5$ sides.
4. Therefore, a pentagon can be divided into equal parts in $5$ ways.
5. A regular pentagon has $5$ lines of symmetry.

Hence, a pentagon has five lines of symmetry.
