How many lines of symmetry does a regular polygon with 20 sides have?
A regular polygon with 20 sides is called an icosagon.
The number of lines of symmetry of a regular polygon is equal to the number of sides.
Therefore, a regular polygon with 20 sides (icosagon) has 20 lines of symmetry.
A regular polygon with 20 sides, also known as an icosagon, has 20 lines of symmetry. Each line of symmetry passes through the center of the polygon and divides it into two symmetrical halves.
To determine the number of lines of symmetry of a regular polygon with 20 sides, you can use the formula:
Number of lines of symmetry = Number of sides / 2
In this case, the regular polygon has 20 sides. So, the number of lines of symmetry would be:
Number of lines of symmetry = 20 / 2 = 10
Therefore, a regular polygon with 20 sides has 10 lines of symmetry.
