What polygon has 120 sides?
What polygon has 120 sides?
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.
How many sides does a regular polygon have if each of its exterior angle is 120 degree?
Answer. if each interior angle is 120 then each exterior angle will 60. As we know that sum of exterior angle of polygon =360, side =360/60=6 . the number of sides=6.
How many diagonals have a regular polygon if each interior angle is 120?
9
∴ Number diagonals =nC2−n=2n(n−3)=26×3=9.
How many sides does the polygon have?
Other Types of Polygons
| Polygon | Number of Sides |
|---|---|
| Triangle | 3 |
| Quadrilateral | 4 |
| Pentagon | 5 |
| Hexagon | 6 |
How many sides does a regular polygon have each of its interior angle is 125 degree?
It has 30 sides. The formula (n-2)×180 can be used to find the sum of the interior angles of ANY polygon where n is the number of sides in the polygon.
How many sides does a regular polygon have if each of its exterior angles is 150?
Therefore, the exterior angle has measure 180∘−150∘=30∘. Therefore, the number of sides of the regular polygon with interior angle 150∘ is 12.
What is polygon formula?
Polygon Formula The sum of interior angles of a polygon with “n” sides =180°(n-2) Number of diagonals of a “n-sided” polygon = [n(n-3)]/2. The measure of interior angles of a regular n-sided polygon = [(n-2)180°]/n. The measure of exterior angles of a regular n-sided polygon = 360°/n.
How many sides are there in a polygon?
Pentagons are a 5 sided shape. Other polygons have different amounts of sides and angles. Here’s a list of other polygons and the number of sides they have….Other Types of Polygons.
| Polygon | Number of Sides |
|---|---|
| Quadrilateral | 4 |
| Pentagon | 5 |
| Hexagon | 6 |
| Heptagon | 7 |
What is a 99 sided shape called?
nonacontakainonagon
What is a 99 sided shape called? In geometry, an enneacontagon or enenecontagon or 90-gon is a ninety-sided polygon. Thus, the 99 sided shape is called nonacontakainonagon or enneacontanonagon. Here, enneaconta is the prefix for the number of sides numbered from 90 to 99.
