Celco 60 Degree Set Square 26cm Clear

This Celco set square provides 30, 60, and 90-degree angles. The 60-degree angle is the defining feature, making it ideal for constructing equilateral triangles and working with standard geometric configurations in maths and technical drawing.

This listing is for one Celco 60-degree set square. If you need both a 45-degree and a 60-degree set square, check whether Celco also offers a paired or bundled maths set option in the Mega Office Supplies range.

The set square is made from strong, transparent acrylic plastic. It is built to withstand regular classroom or studio use. The clear material resists minor flexing and keeps its graduated markings legible over time.

The scale is metric. Graduations along the edges allow you to measure lengths in centimetres and millimetres directly, which suits the Australian curriculum and standard technical drawing requirements.

It suits secondary school students studying maths, geometry, and technical drawing, as well as professionals working in architecture, engineering, or design. The 26cm size is practical for both desk work and larger drafting surfaces.
