Unit 7 Part 2 - Circles Review Notes

Angles in Circles Match the circle's angles to their correct description. Central Angle Inscribed Angle Interior Angle Exterior Angle Solving for Missing ANGLES What is the value of x? Remember central angles EQUAL their arc measure. What is the value of x? Remember inscribed angles EQUAL HALF their arc measure. What is the value of x? Remember interior angles = 1 (Arc + Arc) What is the value of x? Remember exterior angles = 1 (Big Arc - Small Arc) Solving for Missing SEGMENTS Segments in Circles Match each circle's segments to their correct description. Chords Secants Tangents What is the value of x? Remember chords formula is part x part = part x part. What is the value of x? Remember secants formula is outside (whole)= outside (whole).Whole means that the outside number is going to repeat. For example 7(7+6)=10(10+9). What is the value of x? Remember tangents formula istangent = tangent.
