If we link them to the length of a day, the stars don’t quite realign. Then how about a year? The stars do align after a year. That’s about 360 days. I’m king. Make it so… Slide9:  Today we learned about Positive & Negative angles in standard position Co-terminal angles What a degree is Degree conversions Why these are as they are Slide10:  Radians Choice of Mathematicians & Scientists Slide11:  Image Sources Yumigia.
