What do you call a polygon with 9 sides?
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”.
What polygons have lines of symmetry?
Each regular polygon (equilateral triangle, square, rhombus, regular pentagon, regular hexagon etc.) are symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides a regular polygon has. Some figures like scalene triangle and parallelogram have no lines of symmetry.
What is the sum of the interior angles of a nonagon 9 sides?
A nonagon consists of 9 angles. The sum of angles of a nonagon is 1260°.
How many vertices have a nonagon?
9Nonagon / Number of vertices
How many degrees are in a 9 sided polygon?
140 °
To find the value of an internal angle within this polygon, we can just multiply the number of triangles by 180 ° , then divide by the number of internal angles, which is nine. Excellent! So the interior angle of a 9 -sided polygon is 140 ° .
How many angles does a 9 sided polygon have?
How many lines of symmetry does a 8 sided polygon have?
8 lines
Answer: A regular octagon has 8 lines of symmetry.
Does a nonagon have rotational symmetry?
Order 9Nonagon / Rotational 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.
How many lines of symmetry does a polygon of 9 sides have?
And this pattern continues: 1 A regular polygon of nine sides has nine lines of symmetry 2 A regular polygon of ten sides has ten lines of symmetry 3 A regular polygon of “ n ” sides has “ n ” lines of symmetry
How many lines of symmetry does an octagon have?
A regular octagon is an eight-sided polygon with equal length sides. A regular octagon contains eight lines of symmetry, as we can see in the figure below. And this pattern continues: A regular polygon of nine sides has nine lines of symmetry
How many lines of symmetry does a pentagon have?
Lines of Symmetry in a Regular Pentagon A regular pentagon has five sides that are all equal. So, it contains five symmetry lines. Lines of Symmetry in a Regular Hexagon
How many lines of symmetry does a circle have?
A regular polygon has all sides equal, and all angles equal: A line (drawn at any angle) that goes through its center is a Line of Symmetry. So a Circle has infinite Lines of Symmetry.
