First, we will define all the parts of circles and explore the properties of tangent lines, arcs, inscribed angles, and chords. Next, we will learn about angles and segments that are formed by chords, tangents and secants. Lastly, we will place circles in the coordinate plane and find the equation of and graph circles.
