... of what a 45◦ angle looks like. A 1.3-radian angle is certainly less clear. While the three units may seem very different, they all measure the same thing. In fact, we can convert between them because we know that 1 rev = 360◦ = 2π rad . How many degrees does a 1-radian angle span? The constant π is ...
