Quick Answer: How Does A Polygon Get Its Name?

How do you identify a polygon?

Polygons are classified and described by the number of sides, the kind of angles, and whether any of the sides are the same length (or congruent).

Many polygons have special names..

What is an sided polygon?

The segments of a polygonal circuit are called its edges or sides, and the points where two edges meet are the polygon’s vertices (singular: vertex) or corners. The interior of a solid polygon is sometimes called its body. An n-gon is a polygon with n sides; for example, a triangle is a 3-gon.

Which is not a regular polygon?

An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same.

What is a polygon mean?

a closed plane figure bounded by three or more straight sides that meet in pairs in the same number of vertices, and do not intersect other than at these vertices. The sum of the interior angles is (n –2) × 180° for n sides; the sum of the exterior angles is 360°. A regular polygon has all its sides and angles equal.

What is the difference between a polygon and a non polygon?

Thaera, A regular polygon is one where all the sides are congruent and all the interior angles are congruent. An irregular polygon is one that is not regular.

What’s a 13 sided shape called?

tridecagonIn geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon.

What’s a 6 sided shape called?

hexagonMore than Four Sides A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides…

What is a 99 sided shape called?

Polygons with 21 to 99 sides have a different system. Take the prefix for the tens digit (found on the left column), the ones digit (right column below), and then stick a “kai” between them to get (tens)kai(ones)gon . The 3-digit sided polygons are named in a similar fashion. A 100-sided polygon is called a hectogon.

Is a hexagon a regular polygon?

A hexagon is a polygon with 6 straight sides. … A regular hexagon has sides that are all congruent and angles that all measure 120 degrees. This means the angles of a regular hexagon add up to 720 degrees.

Is a rhombus a regular polygon?

A regular polygon must be equilateral (all of its sides are the same length) and equiangular (all of its angles are the same measure). A rhombus is equilateral: all of its sides are of the same length. … A rhombus can never be a regular polygon because it is not equiangular.

What are the polygons names?

Here is a list of polygon names depending on the number of sides they have, starting with three and ending with ten.3 sides – Triangle.4 sides – Quadrilateral.5 sides – Pentagon.6 sides – Hexagon.7 sides – Heptagon.8 sides – Octagon.9 sides – Nonagon.10 sides – Decagon.

What is not a polygon?

A figure or shape is not considered a polygon if it has rounded sides or if its sides intersects at any place other than at the ends of each side. Therefore a circle is not a polygon and an hourglass shape is not a polygon.
