Triangle

The General Rule

Shape | Sides | Sum of Interior Angles |
---|---|---|

Triangle | 3 | 180° |

Quadrilateral | 4 | 360° |

Pentagon | 5 | 540° |

Hexagon | 6 | 720° |

### What is a 108 sided polygon called?

regular pentagon

The triacontagon is the largest regular polygon whose interior angle is the sum of the interior angles of smaller polygons: 168° is the sum of the interior angles of the equilateral triangle (60°) and the regular pentagon (108°).

#### What is a polygon with 1000 sides called?

In geometry, a chiliagon (/ˈkɪliəɡɒn/) or 1000-gon is a polygon with 1,000 sides. Philosophers commonly refer to chiliagons to illustrate ideas about the nature and workings of thought, meaning, and mental representation.

**What is a 500 sided polygon called?**

What is the name of a polygon with…?

# | Name of the Polygon + Geometric Drawing |
---|---|

200 sides | dihectogon |

300 sides | trihectogon |

400 sides | tetrahectogon |

500 sides | pentahectogon |

**Are all polygons 180 degrees?**

A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees. As a result, the interior angles of a regular polygon are all equal to 180 degrees minus the measure of the exterior angle(s).

## How many sides has a heptadecagon?

This document presents Gauss’s insight that it is possible to construct a heptadecagon— a regular polygon with 17 sides—with straightedge and compass.

### What kind of polygon is more than 18 0 O?

A polygon in which at least one angle is more than 18 0 o is called a concave polygon. In a concave polygon, some sides go inside the polygon when extended.In the given figure, A B C D is a concave polygon. Clearly, reflex ∠ C is more than 18 0 o, as shown in the figure.

#### What are the sides of a polygon called?

Each straight line in a Polygon is called its side. A Polygon is classified based on its sides like a triangle, quadrilateral, pentagon, hexagon, heptagon, Octagon, nonagon, and decagon according as it contains 3, 4, 5, 6, 7, 8, 9 and 10 sides, respectively.

**How do you name a 35 sided polygon?**

To “construct” a name, we start with the prefix for the tens digit, follow it by “kai” (the Greek word for “and”), then follow it with the prefix for the units digit, and finally add “gon.”. Example: A 35-sided polygon is called a “triacontakaipentagon.”.

**How many exterior angles does a polygon have?**

The number of interior angles and exterior angles of any polygon is the same. A triangle has three exterior angles; a square has four; our nonagon has nine. An exterior angle is an angle created outside the polygon between one side and a line extended from an adjacent side of the polygon.
