How to Measure a 120-Degree Angle Using a Protractor - Step-by-Step Guide #2009226 (License: Personal Use)

This black-and-white line drawing depicts a standard semicircular protractor with degree markings from 0° to 180°, clearly indicating a 120° angle formed by two rays-one along the baseline (0°) and the other extending to the 120° mark. Arrows show the direction of measurement, and the labeled "120°" reinforces the angle value for educational clarity. The illustration is ideal for teaching foundational geometry concepts in classrooms or self-study materials.

Used in educational resources such as math textbooks, online geometry tutorials, teacher lesson plans, and student worksheets to demonstrate angle measurement technique; matches user intent for learning or reviewing how to use a protractor correctly.
