What is 9 sided polygon called?
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.

What is the name of 10 sided polygon?
decagon
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°.
How many triangles does nonagon have?
A regular nonagon has up to 9 congruent triangles that do not overlap. A nonagon is a type of polygon made up of 9 line segments.
How many acute angles does a nonagon have?
So, the sum of the interior angles of a nonagon is 1260 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)… And there are nine angles…
How many degrees are in a nonagon?
Nonagon/Sum of interior angles
How does a nonagon look like?
It has four equal sides and four right angles, each measuring 90 degrees. A regular nonagon is a nine-sided shape with equal sides and equal angles of 140 degrees each. Each interior angle measure of a regular nonagon is 140 degrees.
What is a 1000000 sided shape called?
megagon
A megagon or 1 000 000-gon is a polygon with one million sides (mega-, from the Greek μέγας, meaning “great”, being a unit prefix denoting a factor of one million).
What is a 12 sided polygon?
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.

What polygon has seven sides and seven angles?
A polygon with seven sides is called a heptagon. A polygon is a closed geometric shape that has at least three sides and angles. Polygons consist of adjoining line segments and are named based on how many sides they have. There are eight polygons that have been officially named…
What is the sum of the interior angles of a nine sided polygon?
A nine-sided polygon is called a nonagon. A regular nonagon has nine equal sides. The 9 equal exterior angles will each be 360/9 = 40 degrees. Each of the interior angles will be 180–40 = 140 degrees and the sum of the 9 interior angles will be 9*140 = 1260 degrees.
What polygon has only one set of parallel sides?
Polygons can also be a parallelograms or trapezoids. A parallelogram is a polygon that has two pairs of parallel sides. A trapeziod is a polygon that has only one pair of parallel sides.
