What is Geometry?​

​Hey... What IS Geometry

Well... Geometry is the part of mathematics that handles shapes and their various special properties.

​

Geometric Shapes are grouped into two types; 2D and 3D shapes​

​2D SHAPES

​3D SHAPES

​2D shapes

​Also known as 'plane shapes'

​2D shapes are flat shapes with only 2 dimensions (length and breadth)

Examples from our everyday life are; square rubber stamps, square tiles on the floor, square paper napkins, chess boards, virtual keyboard keys, and so on.

They are flat shapes because they have no height.​

3D shapes

​Also known as 'solid shapes'

​3D shapes are solid shapes with three dimensions (lenght, breadth and height)

Example from our everyday life; cups, clocks, bottles, Lego^TM bricks, containers, books, and so on.

Note! : Water is not solid because it does not have a fixed shape​.
