In this module, we will be applying previously learned concepts on chords, arcs, central angles, inscribed angles, secants, tangents, segments and sectors of a circle to solve problems. Specifically, you will be able to

1. Solve problems involving chords, arcs, central angles, and inscribed angles of circles; and

2. Solve problems involving tangents and secants of circles.
