Pre-Calc Course, Lec # 9 (Angle Measure)

This is Lecture # 9 of the new series of videos called "Pre-Calculus Course". This lecture discusses 2 ways to measure angles "Degrees" & "Radians", with many other related definitions like Co-terminal angles, complementary and supplementary angles. Several examples are presented to explain those definitions. At the end of each Pre-Calculus lecture, you find some (Old Exams Questions) to check your knowledge and practice more on that topic.

Thank you, I’d like to ask you simple question.
Is there’re any difference between the measurement of angle and the length of angle mathematically?
