7.1b Arc Measure and Arc Length Name:____________________________________ Date:___________ Block:________ 1. What is the difference between an arc measure and an arc length? Find the measures of the given arcs in circle T. 2. mRS = 3. mRPS = 4. mPQR = 5. mQS = 6. mQPS = 7. QTR = Find the arc length of the following. Round to the nearest hundredth. 8. 9. 10. 11. Jamie says that two arcs from different circles have the same arc length if their central angles are equal. Is Jamie correct? Explain your reasoning. (hint: draw a picture!)
