We continued our study of circles today by taking a look at how to calculate other angles involved in circles. These angles occur both inside and outside of circles and are formed from the intersections of two lines/segments. The interior angles are found using the equation : interior angle = 1/2 (arc 1 + arc 2). The exterior angles are found by using the equation: exterior angle = 1/2 (large arc - small arc). We went through 3-4 examples of these types of problems before getting started on the assignment.
