The video tutorial explains the tools used to measure angles, focusing on protractors. It begins by discussing various measurement tools for different quantities and then delves into the concept of angles and their relation to circles. The tutorial introduces protractors as the primary tool for measuring angles, explaining their consistent markings and how they measure angles from 0 to 360 degrees. It also covers different types of protractors, including those measuring up to 180 degrees, and highlights unique features that allow for versatile angle measurement.
