  1. CPCTC http://www.lz95.org/lzhs/Math/knerroth/geometry/Geometry%20Chap%203%20PDF/3.3-CPCTC.ppt#256,1,CPCTC

  2. Match the Corresponding Parts A B C AB BC AC DF DE D EF E F

  3. C.P.C.T.C. • Corresponding • Parts (of) • Congruent • Triangles (are) • Congruent If two triangles are congruent, then their corresponding parts are also congruent. http://www.lz95.org/lzhs/Math/knerroth/geometry/Geometry%20Chap%203%20PDF/3.3-CPCTC.ppt#256,1,CPCTC

  4. Very important!!!! • Before you use CPCTC you must prove or know that the two triangles congruent!!! http://www.lz95.org/lzhs/Math/knerroth/geometry/Geometry%20Chap%203%20PDF/3.3-CPCTC.ppt#256,1,CPCTC

  5. Using CPCTC http://www.lz95.org/lzhs/Math/knerroth/geometry/Geometry%20Chap%203%20PDF/3.3-CPCTC.ppt#256,1,CPCTC

  6. Using CPCTC With your partner write down all congruent parts. http://www.lz95.org/lzhs/Math/knerroth/geometry/Geometry%20Chap%203%20PDF/3.3-CPCTC.ppt#256,1,CPCTC

  7. Find the value of all the angles ΔJKL  ΔMKL J = 3x + 2 JLK = 90° M = 5x - 32 J = JKL = JLK = MLK = MKL = M = 53 37 90 90 37 53
