Protractor with Ruler - Precision Angle Measurement Tool for Students & Drafters #3276065 (License: Personal Use)

The image shows a semi-circular transparent protractor made of durable plastic, with two concentric degree scales (inner and outer) ranging from 0° to 180° for measuring acute and obtuse angles. Below it lies a 10 cm metric ruler with millimeter gradations, enabling precise linear measurements alongside angular work. The clean, high-contrast black markings ensure readability on white or grid paper.

Commonly used in K-12 math classrooms, engineering labs, technical drawing, and DIY projects; supports user intent for learning geometry basics, verifying angle accuracy, or creating scale diagrams.
