The right tools make learning fun. When it comes to math it s much easier to grasp its concepts with a nice geometry set. A protractor gets those angles and circumferences just right. Meanwhile a straight-edge ruler and a triangle ruler both help create lines and nail measurements with precision. Our geometry set of rulers helps identify measurements are effective math tools and are suitable for kids and adults. These drafting tools are great instruments for students teachers artists designers architects engineers construction and more. Make measuring and creating shapes a breeze with the Enday 4-Piece Geometry Set!. The metric ruler set has 4 pieces: A 30 cm or 12-inch ruler a 6.5 (16.5 cm) 30/60-degree triangle ruler another 5.25 (13.3 cm) 45/90-degree triangle ruler and a 6 (15.3 cm) 180-degree protractor. Our triangle ruler protractor and straight-edge ruler drafting tools set are portable and durable. All of its pieces are made with a lightweight plastic material. Each plastic ruler is also engineered so that it can be easily placed inside a knapsack or pencil case. These also feature sharp numerals for consistently accurate and precise measurements. We have kept the plastic material of our 12-inch ruler geometry set transparent so you can see everything beneath it when you draw or measure. Calculate and draw flawless shapes while getting a clear view of what is beneath the protractor or plastic ruler. Trace and draw the ultimate lines angles and circumferences for an accurate equation every time! Choose school supplies and office supplies that get the job done accurately.
