You have learned about the following topics: identifying tangent lines to a circle using properties of tangent lines to solve problems identifying chords, arcs, and central angles using properties of chords, arcs, and central angles to solve problems finding the measures of inscribed angles finding the measures of angles formed by a tangent and a chord finding the measures of angles formed by chords, secants, and tangents finding the lengths of segments associated with circles Reflect on each of these topics answer answer two of the following questions: Which topic in this unit do you feel the most confident about and why? Which topic in this unit has been the most challenging for you and why? Explain a scenario where one topic that you have learned about so far in this unit could be used in real life.
