How to find the estimate of an angle in radians - Help me on math

The video tutorial explains how to measure angles using radians, emphasizing the positive and negative directions of angles. It introduces the concept of radians as a unit of measurement, similar to degrees, and demonstrates how to estimate angles in radians using a circle. The tutorial also clarifies the difference between positive and negative radians and provides examples of estimating angles to the nearest half radian.
