a triangular ruler used for drawing straight lines and angles, commonly available in 30-60-90 and 45-45-90 degree configurations
A drafting triangle is a tool used in technical drawing to create precise angles. It is typically made of plastic or metal and comes in various sizes. The most common drafting triangles are the 30-60-90 degree and 45-45-90 degree types. They are used in combination with a T-square or ruler to draw straight lines at specific angles. Drafting triangles are essential for architects, engineers, and designers, helping them create accurate geometric shapes and angles in their technical drawings and blueprints.
- The architect used the drafting triangle to create the precise 45-degree angle on the blueprint.
- For the building plans, the draftsman carefully measured the angles using a drafting triangle.
- The engineer relied on the drafting triangle to make sure all the lines were straight and angled correctly.
- The designer's drafting triangle ensured that the angles on the technical drawing were exact and aligned.
