We continued our work with circles today by going over how to identify arc types and central angles. We discussed major arcs, minor arcs, and semicircles and how to label each one. We also went over how to find the measurements of these arcs by using the central angles. Our final topic was an illustration of how to use central angles to determine location on the globe and how geometry is used in calculating longitude and latitude.
