How many lines of symmetry does an octagon have?
How many lines of symmetry does an octagon have?
A line of symmetry is the imaginary line that you draw through a shape so that you can fold the image over the line and have both halves match exactly. Any regular shape has as many lines of symmetry as it does sides. Since an octagon has eight sides, the correct answer is 
.
