9.8 CHAPTER9 REVIEW
Finally, we dive into a different shape, circles. First, we will define all the parts of circles and then explore the
properties of tangent lines, arcs, inscribed angles, and chords. Next, we will learn about the properties of angles
within circles that are formed by chords, tangents and secants. Lastly, we will place circles in the coordinate plane,
find the equations of, and graph circles.
