How many lines of symmetry are in a nonagon?
9
Nonagon/Line of symmetry
A regular nonagon has 9 lines of symmetry and a rotational symmetry of order 9, meaning that it can be rotated in such a way that it will look the same as the original shape 9 times in 360°. Nine 40° of rotation about the center.
What are the lines of symmetry on a hexagon?
6
Hexagon/Line of symmetry
A regular hexagon has six rotational symmetries (rotational symmetry of order six) and six reflection symmetries (six lines of symmetry), making up the dihedral group D6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side.
Is a nonagon symmetrical?
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon….Nonagon.

What is the shape of nonagon?
nine sided shape
A nine sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners. The word nonagon comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.
How many vertices have a nonagon?
Nonagon/Number of vertices
Does a hexagon have 6 lines of symmetry?
Answer: A regular hexagon has 6 lines of symmetry. For all regular polygons, the number of lines of symmetry is equal to the number of sides.
How many angles of rotational symmetry does a nonagon have?
Order 9
Nonagon/Rotational symmetry
How do you write a nonagon?
Nonagon = Nona + gon where Nona means nine and gon means sides.
How many intersecting lines does a hexagon have?
The Lemoine hexagon is a cyclic hexagon (one inscribed in a circle) with vertices given by the six intersections of the edges of a triangle and the three lines that are parallel to the edges that pass through its symmedian point.
How many axis of symmetry does a hexagon have?
A regular hexagon has 6 axes of symmetry. A circle has an infinite number of axes of symmetry. The figure below has no axis of symmetry.
How do you calculate the side of a hexagon?
Calculating Hexagon Sides From the Perimeter. Because a regular hexagon has six sides of the same length, finding the length of any one side is as simple as dividing the hexagon’s perimeter by 6. So if your hexagon has a perimeter of 48 inches, you have: 48 inches ÷ 6 = 8 inches. Each side of your hexagon measures 8 inches in length.
What figure has six lines of symmetry?
A hexagon has six such lines: It also has rotational symmetry, because the figure is not changed when it is rotated around a point at the center by any integer multiple of 60 degrees.
