How do you find the bounding box?

The bounding box is rectangular, which is determined by the and coordinates of the upper-left corner of the rectangle and the such coordinates of the lower-right corner. Another commonly used bounding box representation is the -axis coordinates of the bounding box center, and the width and height of the box.

How do you convert angles to radians?

Multiply the number of degrees by π/180. Therefore, 1 degree is equivalent to (π/180) radians. Since you know this, all you have to do is multiply the number of degrees you’re working with by π/180 to convert it to radian terms. You can remove the degree sign since your answer will be in radians anyway.
