NonagonNonagon. In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, "ninth" + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
How many angles does a 10 sided polygon have?
A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440° . An irregular decagon has sides and angles that are not all equal or congruent.
What is a 12 sided polygon called?
dodecagonIn geometry, a dodecagon or 12-gon is any twelve-sided polygon.
What is a 11 sided polygon called?
HendecagonHendecagon. In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka "eleven" and –gon "corner", is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim "eleven".)
nonagon
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 is a polygon with 10000 sides called?
In geometry, a myriagon or 10000-gon is a polygon with 10,000 sides. Several philosophers have used the regular myriagon to illustrate issues regarding thought.
What do you call a 12 sided shape?
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
Does a decagon have 10 sides?
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°.
Is Apeirogon a circle?
“In the limit, a sequence of regular polygons with an increasing number of sides becomes a circle, if the perimeter is fixed, or a regular apeirogon, if the edge length is fixed.”
What does an octagon symbolize?
The octagon and the star octagram were religious symbols for rebirth and resurrection. It was used in baptismal fonts in many churches, large and small. J.C. Cooper states that baptismal fonts were octagonal because the octagon symbolizes renewal, rebirth, regeneration, and transition [1978].
What are the angles of a 8 sided polygon?
The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon. An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees. Because the octagon is regular, all of its sides and angles are congruent.
What do you call a shape with 1 trillion sides?
A teragon is a polygon with 1 trillion sides, it has a Schläfli symbol .
The octagon is also a type of polygon that has 8 sides as well as 8 angles. The octagon is composed of two words – octa and gonia. In which, octa refers to eight and gonia means angles.
What do mathematicians call regular polygon with 8 sides?
A polygon with four unequal sides is called a quadrilateral. A flat image that can be displayed in three dimension is called a hologram. Giga stands for 10 to the 9th power. A Icosahedron has 20 equal sides. Mathematicians call a regular polygon with eight sides, an Octagon.
What is the regular polygon of 8 sides called?
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t {4}, which alternates two types of edges. A truncated octagon, t {8} is a hexadecagon, {16}.
What does a 8 sided polygon look like?
An octagon is an 8-sided polygon (a flat shape with straight sides). First, have a play with an octagon: When all angles are equal and all sides are equal it is regular, otherwise it is irregular
