What does radians in terms of pi mean and how does it look

The video tutorial introduces the concept of radians, explaining that a radian is the radius wrapped around a circle. It discusses how radians relate to π, with half a circle being π radians and a full circle being 2π radians. The tutorial further explores dividing π into fractions, such as halves, quarters, and thirds, to measure angles. It emphasizes the flexibility of breaking radians into various fractional parts, highlighting the common angles used in terms of π.

Explain how π can be divided into quarters.
