What shape has ten sides and ten angles?
What shape has ten sides and ten angles?
decagon
A decagon is a ten-sided polygon with ten vertices and ten angles. Thus, a decagon shape can be defined as a polygon having ten sides, ten interior angles, and ten vertices. Based on the sides of a decagon, they are broadly classified into regular decagons and irregular decagons.
How do you pronounce decagon?
A decagon is a closed shape with ten sides and ten angles. The word decagon comes from Greek roots, deka, or “ten,” and gōnia, “angle or corner.” Any ten-sided shape can be called a decagon, whether it’s a street sign or the doodle you draw in your notebook during math class.
What is the interior of a 10 Gon?
The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon.
What does a 10 sided shape look like?
A regular decagon has all sides of equal length and each internal angle will always be equal to 144°. Its Schläfli symbol is {10} and can also be constructed as a truncated pentagon, t{5}, a quasiregular decagon alternating two types of edges.
Is there a shape with 11 sides?
(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”.) In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon.

How many sides do a decagon have?
ten
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 is the sum of a 10 sided shape?
1440°
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°.
What is a 7 sided shape called?
heptagon
In geometry, a heptagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using “sept-” (an elision of septua-, a Latin-derived numerical prefix, rather than hepta-, a Greek-derived numerical prefix; both are cognate) together with the Greek suffix “-agon” meaning angle.
What is a 9 and 10 sided shape called?

What are all the polygons names?
In geometry, the polygon is the shapes. The number of shapes is available in polygon. The names are triangle, quadrilateral, heptagon, hexagon, pentagon, octagon, nonagon, decagon etc.
What shape has 20 sides?
In geometry, an icosahedron (/ˌaɪkɒsəˈhiːdrən, -kə-, -koʊ-/ or /aɪˌkɒsəˈhiːdrən/) is a polyhedron with 20 faces.
What is a 10 sided polygon?
Decagon Definitions 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. An irregular decagon has sides and angles that are not all equal or congruent. A convex decagon bulges outward, with no interior angle greater than 180° 180 °.
What is the largest polygon?
Graham’s biggest little hexagon is the largest possible (not necessarily regular) convex hexagon with polygon diameter 1 (i.e., for which no two of the vertices are more than unit distance apart). It is therefore the biggest little polygon for the case .
