What is the 20 sided shape called?
2nd century B.C.–4th century A.D. A number of polyhedral dice made in various materials have survived from the Hellenistic and Roman periods, usually from ancient Egypt when known. Several are in the Egyptian or Greek and Roman collections at the Museum.
- The icosahedron – 20-sided polyhedron – is frequent.
- Most often each face of the die is inscribed with a number in Greek and/or Latin up to the number of faces on the polyhedron.
- Nothing specific about the use of these polyhedra is preserved, so theories are built on clues provided by some variant examples.
One unusual example uses Greek words, a few of which resemble those associated with throws of the astragals (knucklebones), and this has led to suggestions they were used for games. Another remarkable example discovered in Dakhleh Oasis in Egypt in the 1980s records an Egyptian god’s name in Demotic (the Egyptian script of these late periods) on each face.
Divination – seeking advice about the unknown from the supernatural – seems to be the most likely purpose for the Dakhleh die: the polyhedron might have been thrown in order to determine a god who might assist the practitioner. Indeed, even the dice with simple letters might relate to divination: a Greek oracle book composed in in the 2nd or 3rd century A.D.
refers to throwing lots to obtain a number that would, through certain algorithms, lead to ready-prepared oracle questions and responses.

What is a 17 sided shape called?
The regular polygon of 17 sides is called the heptadecagon, or sometimes the heptakaidecagon. Gauss proved in 1796 (when he was 19 years old) that the heptadecagon is constructible with a compass and straightedge, Gauss’s proof appears in his monumental work Disquisitiones Arithmeticae., where the are distinct primes of the form

known as Fermat primes, Constructions for the regular triangle ( ), square ( ), pentagon ( ), hexagon ( ), etc., had been given by Euclid, but constructions based on the Fermat primes =17″> were unknown to the ancients. The first explicit construction of a heptadecagon was given by Erchinger in about 1800. The trigonometric functions and are both algebraic numbers of degree 8 given respectively by The heptadecagon with unit edge lengths has inradius and circumradius given by both of which can be expressed in terms of finite root extractions. They can also be expressed as the largest roots of the algebraic equations

The following elegant construction for the heptadecagon (Yates 1949, Coxeter 1969, Stewart 1977, Wells 1991) was first given by Richmond (1893).1. Given an arbitrary point, draw a circle centered on and a diameter drawn through,2. Call the right end of the diameter dividing the circle into a semicircle,3. Construct the diameter perpendicular to the original diameter by finding the perpendicular bisector,4. Construct a quarter of the way up,5. Join and find so that is a quarter of,6. Find so that is,7. Construct the semicircle with diameter,8. This semicircle cuts at,9. Draw a semicircle with center and radius,10. This cuts the line segment at,11. Construct a line perpendicular to through,12. This line meets the original semicircle at,13. You now have points and of a heptadecagon.14. Use and to get the remaining 15 points of the heptadecagon around the original circle by constructing,,,,,,,,,,,,,,,, and,15. Connect the adjacent points for to 17, forming the heptadecagon. This construction, when suitably streamlined, has simplicity 53. The construction of Smith (1920) has a greater simplicity of 58. Another construction due to Tietze (1965) and reproduced in Hall (1970) has a simplicity of 50. and simplicity 45. The construction problem has now been automated to some extent (Bishop 1978).

What is a 11 and 12 sided shape called?
What is an 11 and 12 sided shape called? Answer Verified Hint: We are required to find the names for 11 and 12 sided shapes. Firstly, we draw a polygon of 11 sides and label the points. Then, draw the polygon of 12 sides and label the points to get the desired result.
- Complete step-by-step answer: A polygon, in mathematics, is a geometric figure that has a finite number of sides.
- The sides of any polygon are line segments connected at either end.
- The point of intersection of two or more points is called the vertex or the corner of the polygon.
- The word polygon is composed of two words ‘poly’ meaning many and ‘gon’ meaning sides.
Examples of polygons: 1. Triangle 
The triangle is a polygon because it has three sides and three angles.2. Square The square is a polygon because it has four sides and four angles.In geometry, the shape with 11 sided shape is called a hendecagon. It is also called as undecagon and endecagon.Hendecagon is a polygon that is made up of 11 sides and 11 angles. The sum of internal angles of a hendecagon is $ ^ }$The perimeter of the 11 sided shape is the product of 11 and side length.The hendecagon is diagrammatically represented as follows, 
From the above figure,We can conclude that the figure has 11 vertices namely, Vertices: A, B, C, D, E, F, G, H, I, J, K.We can conclude that the figure has 11 edges namely, Edges: AB,BC, CD, DE, EF, FG, GH, HI, IJ, JK, KAIn geometry, the shape with 12 sided shape is called a dodecagon. 
From the above figure,We can conclude that the figure has 11 vertices namely, Vertices: A, B, C, D, E, F, G, H, I, J, K, L.We can conclude that the figure has 11 edges namely, Edges: AB,BC, CD, DE, EF, FG, GH, HI, IJ, JK, KL, LA.$\therefore $ 11 sided and 12 sided polygons are called Hendecagon and Dodecagon respectively.
