1 Lesson: Angle Measures and Segment Lengths in Circles
Unit 9: Circles Lesson: Angle Measures and Segment Lengths in Circles Essential Questions: How are the angles and arcs in a circle related? How can you find the measure of angles, arcs, & chords when lines intersect a circle?

2 Circles Goals: To find the measures of inscribed angles. To find the measure of angles formed by a tangents, secants, and chords. To find the length of segments associated with circles. Essential Understandings: Angles and the arcs formed have a special relationship. There is a special relationship between intersecting chords, secants and tangents.
