Description
This MicroSim illustrates the relationship between degrees and radians, the two most common ways to measure angles. A slider allows students to rotate a line around a circle while observing both the degree measurement and the radian measurement. Alternating colored arcs along the circumference show each radian segment, demonstrating that there are 2π (approximately 6.28) radians in a full circle.

Prompt
Please generate a new p5.js MicroSim that will be used in our high-school geometry textbook. This MicroSim illustrates the different ways we measure angles comparing both degrees and radians. There is a single slider that changes the angle of a line in a circle at the center of the drawing area. As the slider moves, the line rotates around the circle. The angle starts at 0 degrees and ends at 360 degrees. Place alternating blue and orange segments arcs along the circumference are of distance 1 radian. The diagram illustrates the fact that there are 2 pi radians in a circle. The title is "Comparing Degrees and Radians".
