This PowerPoint presentation investigates the fundamental trigonometric angle measurement known as a radian. You will learn what a radian is, how it is derived, and the relationship between radians and degrees.
After learning the definition of an angle you will then review some basic geometric concepts. Using the definition of an angle and the geometric concepts a radian is defined and an animation shows how a radian is derived in a circle.
The relationship between degree and radian measurement is explored and it is shown how to convert from one unit of measurement to another.
