Geometry

Geometry is a topic that you study in mathematics at school. In geometry you learn about shapes, lines, solids, angles and surfaces.

The first few shapes that you will come across include squares, triangles and circles. These are known as 2-dimensional shapes as they are flat.

What is a vertex?

A vertex is a corner on a two dimensional (2D) or three dimensional (3D) shape.

Squares

A square is one of the first shapes that you will come across in study. It is made up of four equal length lines which are put together so that two lines go across in parallel and two lines go down in parallel.

The area of a square can be found by multiplying one length of the square by any of the other three lengths.
