Lightweight design with smoothly rounded edges reduces sharp hazards while maintaining portability, making it a safe and easytocarry geometry tool for students and educators. Essential for students, teachers, and professionals such as engineers or architects who require a clear angular measuring tool in the classroom, workshop, or creative studios. Multifunctional geometry measuring ruler and math teaching aid that doubles as a straightedge, enabling artists, architects, and enthusiasts to tackle complex diagrams and craft projects. Clearly marked scales remain visible in low light conditions, suitable for homework, engineering drafting, outdoor STEM activities, or technical drawing projects. Practical use scenarios: Geometry homework and classroom activities requiring precise angles and measurements. Engineering drafting, architectural planning, or iterative design in workshops or studios. Outdoor STEM experiments and craft projects where a reliable straightedge and measurement tool is needed.
