A regular pentagon has five lines of reflectional symmetry , For more information, see Construction of a regular pentagon. I found an answer from www. Mar 20, There are 5 lines of symmetry in a regular pentagon.
How many lines of symmetry does a regular quadrilateral have? For more information, see Number of lines of symetry in a regular pentagon? In geometry , a pentagon is any five-sided polygon or 5-gon. A shape has a line of symmetry when the folded part sits perfectly on top with all edges matching. The first three lines are not lines of symmetry. The folded part does not sit perfectly on top of the other part.
Only the fourth shape has a line of symmetry. A square is a regular polygon. It has four lines of symmetry and four sides. A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides.
