## What is a perfect shape?

From Wikipedia, the free encyclopedia.

A two-dimensional equable shape (or perfect shape) is one whose area is numerically equal to its perimeter.

For example, a right angled triangle with sides 5, 12 and 13 has area and perimeter both have a unitless numerical value of 30..

## Is a circle a regular shape?

Regular means predictable, with the fewest possible variations. So yes, a circle is about as regular as a shape can be. You can define a circle with just a center and a radius. Compare this, for example, to the shape of a human body, which would be rather irregular, requiring a lot of information to describe it fully.

## How can you tell if its a polygon?

A polygon is a closed figure where the sides are all line segments. Each side must intersect exactly two others sides but only at their endpoints. The sides must be noncollinear and have a common endpoint.

## Can a polygon have an open side?

But first, we need to know what polygons are: polygons are several straight segments placed together. Polygons can be classified as open or closed. A polygon is open when the segments do not all connect at the beginning and end.

## What is a circle considered?

Euclid’s definition A circle is a plane figure bounded by one curved line, and such that all straight lines drawn from a certain point within it to the bounding line, are equal. The bounding line is called its circumference and the point, its centre.

## Does a polygon have to be closed?

Polygons. A polygon is any closed, 2-dimensional figure that is made entirely of line segments that intersect at their endpoints. Polygons can have any number of sides and angles, but the sides can never be curved.

## What’s a 6 sided shape called?

hexagonA 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…

## Which shape has 3 more sides than a triangle?

## What’s a 12 sided shape called?

dodecagonIn geometry, a dodecagon or 12-gon is any twelve-sided polygon.

## Is a triangle a polygon yes or no?

As you learned in the last lesson, a triangle is the simplest polygon, having three sides and three angles. The sum of the three angles of a triangle is equal to 180 degrees. Triangles are classified by sides and by angles.

## What is the most perfect shape?

circleBecause of its symmetry the circle is considered as the perfect shape. It is the symbol for the total symmetry of the divine (sic!). The Greek scholar Proclus (500 AC) wrote: “the circle is the first, the simplest and most perfect form”.

## What is a closed shape called?

Let’s learn! In geometry, a closed shape can be defined as a enclosed shape or figure whose line segments and/or curves are connected or meet. They start and end at the same point.

## Is any 6 sided shape a hexagon?

In geometry, a hexagon (from Greek ἕξ hex, “six” and γωνία, gonía, “corner, angle”) is a six-sided polygon or 6-gon. … The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.

## Can a polygon have 5 vertices and 3 sides?

The triangle has 3 sides and 3 vertices. The quadrilateral has 4 sides and 4 vertices. The pentagon has 5 sides and 5 vertices.

## Is a circle a polygon with infinite sides?

No, a circle is not a regular polygon with an infinite number of sides.
