What polygon has 10 sides and angles?
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°. A self-intersecting regular decagon is known as a decagram.
What’s a 9 sided shape called?
Nonagon
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 interior angle of 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 degrees is a 9 sided shape?
Excellent! So the interior angle of a 9 -sided polygon is 140 ° .

What called polygon with 999 sides?
What do you call a 9999-sided polygon? A nonanonacontanonactanonaliagon . While polygons are important in computer graphics, what’s special about a 9999-gon? Well, not much really, but it made me think about the nomenclature for polygons: the word “polygon” comes from the Greek polygōnon, meaning “many-angled”. Polygons are usually named according to the number of sides, combining a Greek-derived numerical prefix with the suffix -gon, e.g. pentagon (5-gon), dodecagon (12-gon) or
What is the shape with 9 sides?
A: A nonagon is a closed shape that has nine sides. If it is a regular nonagon, all nine sides are the same length, and all the angles are equal.
