Geometry

Geometry is a branch that deals with shapes, sizes, and the properties of figures.

Shape –

A one or two-dimensional form of an object or its outline or outer boundary or outer surface is called shape.

Curve

A continuous and smooth flowing shape or a line in a plane having a bent or turns in it is called A curve.

Types
(1) Simple Curve

        (i) Open Curve

        (ii) Closed Curve

(2) Non-simple or complex Curve

Types of Curves

Simple Curve: A curve changes direction but does not cross or intersect itself while changing direction is called a simple curve. 

A simple curve can be open and closed both.

Non-simple or complex curves: A curve that crosses its own path is called a non-simple or complex curve. It means the curve intersects itself while changing its direction.

Open curve: A curve which does not enclose any area within itself and has two endpoints is called open curve. 

Closed curve: A curve without end points and encloses an area (or a region) is called close curve.

It is formed by joining the end points of an open curve together. The best example of closed curves are circles , ellipses are formed from closed curves.
