Question

How many lines of symmetry does an octagon 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. An octagon is a polygon that has $8$ sides.
4. Therefore, an octagon can be divided into equal parts in $8$ ways.
5. A regular octagon has $8$ lines of symmetry.

Hence, an octagon has eight lines of symmetry.
