  1. M≅ Q N≅ R K≅ S L≅ P congruent corresponding parts o 90 12 in o 60

  2. 3 cm o 80 o 100 4 cm ABC ≅ LMK by SAS HGJ ≅ QPN by SSS

  3. The congruent sides needs to be written in the proper order. (5x + 15) = 105 -15 -15 5x = 90 5 5 x = 18

  4. These are congruent by SSS x - 6 = 4 +6 +6 x = 10 These are congruent by ASA 2x + 6 = 32 -6 -6 2x = 26 2 x = 13 These are congruent by ASA 2x - 24 = x -x -x x - 24 = 0 +24 +24 x = 24

  5. These are congruent by SAS These are congruent by SSS Equality and congruence mean that something is the same. Equality is used with numbers. Congruency means that something is the same size.

  6. 90 + 90 + x + x + 105 = 540 285 + 2x = 540 -285 -285 2x = 255 2 2 x = 127.5 o 109 + 72 + 76 + x = 360 257 + x = 360 -257 -257 x = 103 90 + 90 + 101 + 101 + x = 540 382 + x = 540 -382 -382 x = 158 o o (18-2) 180 18 16 180 18 16 180 18 2880 18 o = = = 160 =
