  1. Arcs and Chords Section 10-3

  2. TV WS. Find mWS. Example: Applying Congruent Angles, Arcs, and Chords = 88°

  3. Example: Applying Congruent Angles, Arcs, and Chords C  J, andmGCD  mNJM. Find NM.

  4. PT bisects RPS. Find RT. Example: RT = 12

  5. mCD = 100 Example: Find each measure. A B, and CD EF. Find mCD.

  6. In a circle or congruent circles, two chords are congruent if and only if they are equidistant from the center of the circle

  7. Example: Find NP. NP= 2(15) = 30

  8. Example: Find QR to the nearest tenth. QR= 2(17.3) = 34.6

  9. Arcs, Chords, and Polygons • The chords of adjacent arcs can form a polygon. The polygon is inscribed in the circle and the circle circumscribes the polygon
