With a protractor, the angles of any shape can found where two lines meet and form a corner. The shapes themselves can also be identified from this by matching the angles to the shape properties.

Learn how to identify and calculate angles around a point with this Year 5 Maths guide from BBC Bitesize.

This design element enhances the functionality of the tool, enabling users to find precise angles and marking center points, a feature not typically found in a standard protractor.
