It is also a transcendental number, meaning that it is not the root of any non-zero, polynomial that has rational coefficients. We saw different types of angles in the “Angles” section, but in the case of a circle, there, basically, are four types of angles. The angle unit choices are degree (deg), radian (rad). In the case of a pentagon, the interior angles have a measure of (5-2) •180/5 = 108 °.
