Trigonometry – Definition of a Radian

We’ve seen how to measure angles in degrees using a protractor: However, the degree is a fairly arbitrary unit of measurement – who decided to divide the circle into 360 parts? Why can’t the circle be divided into 100 parts? 1000 parts? Radian measure is an alternative way to measure angles. Instead of dividing the…
