how many lines of symmetry in pentagon
Answer by GB. A regular pentagon has 5 lines of symmetry, running from each vertex to the midpoint of the opposite side. These lines are not to be confused with the five lines it takes to draw a pentagon. Every regular polygon has as many lines of symmetry as there are lines in the polygon. An irregular pentagon may have none or 1 line of symmetry. A <b>regular pentagon</b> has 5 lines of symmetry, running from each vertex to the midpoint of the opposite side.
