Presentation Transcript

• In your own words, define:

• 1) intercepted arc

• 2) secant

• 3) chord

• SWBAT use theorems regarding angles of circles to find missing measurements.

• Cumulative Review 4 due this Friday at the beginning of class

• Let’s fill out the summary worksheet…

• It is coming your way on the next slide.

• 1) Central angle mAVC = mAC

• 2) Inscribed angle mAVC = (1/2)mAC

• 3) Vertex-on angle (acute) mAVC = (1/2)mAV

• 4) Vertex-on angle (obtuse) mAVC = (1/2)mADV

• 5) Vertex-in angle mAVC = (1/2)(mAC +mBD)

• 6) Vertex-out angle (secant) mAVC = (1/2)(mBD –mAC)

• 7) Vertex-out angle (sec/tan) mAVC = (1/2)(mBC –mAC)

• 8) Vertex-out angle (tangent) mAVC = (1/2)(mABC – mAC

• Use your summary worksheet to get through as much as possible of Practice 12-5 Example Exercises (#1, 3, 5, 7 only)
