Find the reference angle of an angle in radians in standard form

The video tutorial emphasizes the importance of repetition and pattern recognition in problem-solving. It explains how to sketch the angle 2π/3 by breaking π into thirds and identifying the reference angle as the positive acute angle between the terminal side and the X axis. The tutorial highlights that the reference angle is always positive and acute, without direction.

What is a reference angle and how is it determined?

Describe the relationship between the terminal side and the X axis in the context of reference angles.
