U1L02P1FST Part B – Unit 1 Lesson 02 Radian and Degree Measure

### Lesson 2: Radian and Degree Measure :

Lesson 2: Radian and Degree Measure Essential Questions for this Lesson: How does Degree Measure compare to Radian Measure? What is the procedure to convert from Radians to Degrees and from Degrees to Radians?

### How does radian measure compare to arclength? :

How does radian measure compare to arclength? The standard introduction to radian measure and unit circle trigonometry involves "wrapping" the real t number line around the unit circle with equation x2 + y2 = 1. This Demonstration illustrates that wrapping. The number line is wrapped with integer radian values and then also in terms of /2. The t number line is colored to enhance the visual understanding of which numbers end up where on the unit circle.

### Example: Draw a figure depicting an angle of 2/3. :
