## How do you explain circle to a child?

A circle is a shape that is made up of a curved line. It’s round, and all points on the curved line are an equal distance from the center point. This shape is two-dimensional, which means it’s flat.

## Who invented circle?

The greeks considered the Egyptians as the inventors of geometry. The scribe Ahmes, the author of the Rhind papyrus, gives a rule for determining the area of a circle which corresponds to π = 256 /81 or approximately 3. 16. The first theorems relating to circles are attributed to Thales around 650 BC.

## What is the best definition of a circle?

A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

semicircleIn mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn).

## Why is a circle 2d?

Circle: A 2D shape whose points are always the same distance from some central point. … Thus, the area of a circle, its radius, its diameter, and its circumference are all related. Using any one of these values, we can find the other three! Chord: Any line segment that connects two points on a circle.
