Concepts on circles are basic necessity in many fields such as construction, landscaping and engineering. Aside from these concepts, the properties of lines and its subsets and their relationship to circles are important. These are the lines that either touch or intersect circles.
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.
