Protractor Tool - Precision Angle and Length Measurement Guide #2009685 (License: Personal Use)

This transparent plastic protractor features a 180-degree arc marked in 1-degree increments and a straight edge ruler calibrated in centimeters (0-10 cm), enabling simultaneous angular and linear measurements. The central hole aligns with the vertex of an angle, while the dual-scale design supports both metric and angular geometry tasks. Its durable, lightweight construction makes it ideal for classroom, drafting, and fieldwork applications.

Used in educational settings (math/science classrooms), engineering drafting, architecture, and DIY projects where users need to measure or draw angles accurately; matches intent for “how to use a protractor” or “geometry tools.”
