What is it?A protractor is a tool shaped like a half-circle (180°) or full circle (360°), marked with degrees (°). Engineers, builders, and scientists use it to measure or draw ang les. Where do I use it? Pitching Machine – Measure launch angles and compare how angle changes affect distance. Hydraulic Loader – Test lifting arms at different angles to understand force and stability. Why is it important?Angles are everywhere — from bridges and cranes to rockets and satellites. A protractor helps students understand how direction and tilt can completely change outcomes in engineering. STEM Skill Focus Connect maths with motion and design. Collect and compare angle data to identify patterns. Show more
