Triangle Ruler with Protractor

A transparent plastic geometry triangle, commonly known as a set square, featuring an integrated protractor. This versatile tool is designed for precise drawing and measurement in geometry, technical drawing, and mathematics. It includes standard centimeter markings along its edges, ranging up to 11 cm, and a central semicircular protractor with angle measurements from 0 to 180 degrees. A visible grid pattern covers the surface for easy alignment and parallel line drawing. The text 'Dirks Geodreieck' and 'Made in Germany' are inscribed on its surface, indicating its origin and brand. It's an essential instrument for students, architects, and engineers alike.
