Unit 10: Circles


In this unit, you will study circles. Circles have many properties and additional pieces that make them extremely useful for solving problems. You will use various discovery techniques to determine these relationships. Amongst the pieces you will study are central and inscribed angles, arcs, chords, tangents, and secants. You will also use these special pieces and their properties to solve real world applications.
