Understanding basic geometric shapes is an essential part of learning graphical communication and technical drawing. These shapes form the foundation for more complex constructions, projections, and design tasks. In this section, you will explore the key properties and classifications of common 2D shapes including triangle constructions, quadrilaterals and the parts of a circle. Recognising and accurately drawing these shapes is important for students studying geometry, engineering drawing, architecture, and other STEM subjects. Each group of shapes is introduced with clear explanations and diagrams to help you build confidence and visual understanding as you prepare for more advanced graphical work.
Each of the links above takes you to a focused section that explains the main types of shapes within that group, along with diagrams and key characteristics. By studying these categories, such as the differences between equilateral, isosceles, and scalene triangles, or the properties of regular polygons and quadrilaterals, you will develop a deeper understanding of how shape, symmetry, and structure play an important role in both mathematics and design. These shape groups are also essential for interpreting technical drawings and preparing for tasks such as orthographic projection or solid geometry construction.
