Learn how to draw different 2D shapes and how to describe it. Recognise 2D and 3D shapes Practise recognising 2D and 3D shapes. Vertical lines of symmetry Learn how the mirror line can help you to ...

2-dimensional shapes - Edexcel 2-dimensional shapes are flat. The perimeter of a 2D shape is the total distance ... Circle theorems are used in geometric proofs and to calculate angles.

We'll look at these first and then at types of geometric modelling used in CAD. Originally, CAD was all in 2D, making use of geometric shapes like lines, rectangles, arcs, and circles to create ...
