What are the kinds of polygon with meaning?
Kinds of polygons with their meanings are: Convex (all diagonals are internal), concave (at least one diagonal is outside the shape), equilateral (equal sides), equiangular (equal angles), regular (equal angles and sides), irregular, (no equal angles and sides), triangle (3 sides), quadrilateral (4 sides), pentagon (5 sides), hexagon (6 sides), heptagon (7 sides), octagon (8 sides), enneagon or nonagon (9 sides), decagon (10 sides), hendecagon (11 sides), dodecagon (12 sides), tridecagon or triskaidecagon (13 sides), tetradecagon or tetrakaidecago (14 sides), pendedecagon (15 sides), hexdecagon (16 sides), hepdecagon (17 sides), ocdecagon (18 sides), enneadecagon (19 sides) and icosagon (20 sides).
How many sides does a regular polygon have that has an angle of rotation equal to eighteen degrees?
360/18 = 20 sides, or any multiple of 20 sides.360/18 = 20 sides, or any multiple of 20 sides.360/18 = 20 sides, or any multiple of 20 sides.360/18 = 20 sides, or any multiple of 20 sides.
What polygon has 12 sides and 12 vertices?
dodecagon * * * * * No, a dodecagon has 20 vertices! One possible answer is a pyramid whose base has 11 sides.
What is a n-gon 20-gon and decagon?
They are the names of polygons with differents number of sides
What are the polygons with 11-20 sides?
31
What is polygons has a 20 sides?
Icosagon
What are the 20 polygons?
Hendecagon has 11 sides,dodecagon has 12 sides,triskaidecagon has 13 sides,tetradecagon has 14 sides,pentadecagon has 15 sides,hexadecagon has 16 sides,17 sides is heptadecagon,octadecagon have 18 sides,enneadecagon has 19 sides,20 sides is called as icosagon. The prefix of that 9 polygons is Greek. A polygone with 4 sides is called a quadrilateral.
Names of polygons with 11 sided to 20 sides?
11 Undecagon, Hendecagon 12 Dodecagon 13 Tridecagon, Triskaidecagon 14 Tetradecagon, Tetrakaidecagon 15 Pentadecagon, Pentakaidecagon 16 Hexadecagon, Hexakaidecagon 17 Heptadecagon, Heptakaidecagon 18 Octadecagon, Octakaidecagon 19 Enneadecagon, Enneakaidecagon 20 Icosagon
Why icosagon have 20 sides?
For the simple reasons that polygons are named after the number of sides, and the Greek prefix "icosa" means twenty!For the simple reasons that polygons are named after the number of sides, and the Greek prefix "icosa" means twenty!For the simple reasons that polygons are named after the number of sides, and the Greek prefix "icosa" means twenty!For the simple reasons that polygons are named after the number of sides, and the Greek prefix "icosa" means twenty!
Is there 20 sides on a decagonal pyramid?
No. 11 sides.
How many vertices would there be if you had a 20-sided polygon?
Polygons have the same number of vertexes/vertices as the sides. So, A 20 sided polygon will have 20 vertexes/vertices.
What are the mathematical names of the first ten polygons and their properties?
All polygons have 3 or more sides having exterior angles that add up to 360 degrees and the first 10 can be classed as follows in order of their geometrical names, number of sides, sum of interior angles and number of diagonals:- 1 Triangle: 3 sides, 180 degrees and no diagonals 2 Quadrilateral: 4 sides, 360 degrees and 2 diagonals 3 Pentagon: 5 sides, 540 degrees and 5 diagonals 4 Hexagon: 6 sides, 720 degrees and 9 diagonals 5 Heptagon or Septagon: 7 sides, 900 degrees and 14 diagonals 6 Octagon: 8 sides, 1080 degrees and 20 diagonals 7 Nonagon: 9 sides, 1260 degrees and 27 diagonals 8 Decagon: 10 sides, 1440 degrees and 35 diagonals 9 Undecagon: 11 sides, 1620 degrees and 44 diagonals 10 Dodecagon: 12 sides, 1800 degrees and 54 diagonals Note that all polygons can be regular, irregular, congruent or similar
What are the names and number of sides of all the polygons?

What is the name of a 21 side polygon?
The term for a 21 sided polygon is an icosikaihenagon. Icosi is the Greek for the numerical 20 and henagon means 1.
Can you name all the polygons?
Not really, because there are an infinitely large number of polygons. Just keep adding another side to the last one you had and you can go on forever. There are special names for a small group of polygons, starting with one that has three sides, the triangle, and continuing on to four sides (quadrilateral), five sides (pentagon), six (hexagon), and even eight (octagon) or ten (decagon). Once you get past that group, you just name a polygon by the number of sides it has. You call it a 20-gon, or a 30-gon.With the variable n representing the number of sides. There are also Shapes called quadrilaterals which are a group of 4 sided shapes including a square, a rectangle a trapezium and many more! That is what I know and what I can tell you!
