In this lesson I will be teaching you about segment lengths in circles. The previous lessons in this chapter were focused on angle and arc measure but in this section we will be focusing on lengths. Now the lengths we will be studying will be those of chords, secants and tangents. Like the previous lesson on other angles in circles there will be many formulas you will need to know. Also the formulas are easy to confuse so you must be really careful on your selection of a formula for a problem. Additionally we will be using algebra equations to solve problems- so never feel bad if you need to review your algebra skills before a lesson.
