  1. TEOREMA PYTHAGORAS Oleh: YORA MIRTHA FANI 0700297

  2. SEGITIGA SIKU-SIKU A Hypotenusa = sisi miring c b a Perhatikansegitiga ABC disamping ! c merupakansisimiring (hypotenusa) a dan b merupakansisi-sisitegak segitiga. C B

  3. MENENTUKAN TEOREMA PYTHAGORAS Perhatikanlahpersegidisampingini! a b Perhatikan 4 buahsegitigasiku-siku! a Bagaimanadenganluasdaerahpersegiluar? b c b a a b NEXT

  4. c a b a b Luasdaerahpersegiluar = = 4 × Luasdaerahsegitigasiku- siku + luas daerahpersegidalam b a 4 + × a b

  5. Denganmenjabarkanluaspersegi, diperoleh: Luaspersegi = Luasdaerahpersegiluar sisi× sisi = 4× Luasdaerahsegitigasiku-siku + Luas daerahpersegidalam (a + b) (a + b) = 4 ( ab) + c2 a2 + 2ab + b2 = 2 ab + c2 a2 + b2 = c2 Teorema Pythagoras

  6. PENERAPAN TEOREMA PYTHAGORAS Sebuahkapalberlayar 10 km kearahselatan.
