**The World of Geometric Shapes**

**A geometric shape is the geometric information which remains the location, scale, and reflection of an object.**

It helps us to describe each shape with all their sides and angles.

Circle

A circle is a simple closed curve which divides the plane in two regions: an interior and an exterior.

The term "circle" may be used to refer only a part of the figure or the whole figure including its interior.

Square

A square is a regular quadrilateral, which means that it has four equal sides and four equal angles.

It is like a type of rectangle because both are made up of four straight sides that are the same length and that has four right angles.

Triangle

A triangle is a polygon with three edges and three verticals.

There are 3 types of triangles:

Isosceles:

Two sides equal

Equilateral:

All sides equal

Scalene:

No sides equal

Rectangle

A rectangle is any quadrilateral with four right angles, every angle is a right angle (90°)

Hexagon

In geometry an hexagon, is a polygon with six edges and six vertices.

It has no curved sides and the shape must also be closed.

Pentagon

A pentagon is any five-sided polygon. The sum of the internal angles in a simple pentagon is 540°.

When all angles are equal and all sides too it is regular, otherwise it is irregular.
