What is a 1000000000000000 sided shape called?

Regular chiliagon
Chiliagon

Regular chiliagon
A regular chiliagon
Type Regular polygon
Edges and vertices 1000
Schläfli symbol {1000}, t{500}, tt{250}, ttt{125}

How many corners does a 20 sided polygon have?

20 vertices
So your 20 sided polygon(called an icosagon). 20 vertices. you can’t draw from the vertex to itself or either of the 2 consecutive vertices…. leaving 17 vertices from each vertex.

What is the shape of a D20?

ICOSAHEDRON
ICOSAHEDRON. The signature die of Dungeons & Dragons, and taller than its siblings, the D20 rolls further because it is the most spherical. The faces are equilateral triangles.

What’s a 20 sided dice called?

icosahedron
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.

What is a polygon with 20 sides called?

In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.

What is a trillion sided shape called?

Regular megagon
Megagon

Regular megagon
A regular megagon
Type Regular polygon
Edges and vertices 1000000
Schläfli symbol {1000000}, t{500000}, tt{250000}, ttt{125000}, tttt{62500}, ttttt{31250}, tttttt{15625}

What’s bigger than a dodecahedron?

In geometry, the rhombicosidodecahedron, is an Archimedean solid, one of thirteen convex isogonal nonprismatic solids constructed of two or more types of regular polygon faces. It has 20 regular triangular faces, 30 square faces, 12 regular pentagonal faces, 60 vertices, and 120 edges.

What is 20 sided polygon called?

How many sides are in a star?

5 sides
This is the regular star polygon (5 sides with 2 skips). The numbers 5 and 2 are relatively prime.

What shape is a D12?

rhombic dodecahedron
These d12 dice have twelve rhombus-shaped faces numbered 1-12. The shape is a fully-symmetrical polyhedron (an isohedron) known as a rhombic dodecahedron, which is closely related to both the cube and the octahedron.

What shape is a d100?

The d100 from the standard 7-dice set is a pair of 10-sided dice (in the standard pentagonal trapezohedral shape), one of which is numbered with the integers from 1 to 10 and the other of which has faces numbered in multiples of 10 (00, 10, 20, 30 and so on to 90).
