15 20n sol? – supliment congruent angles are congnents proof By hypothesis lef LABC, L DEE: 2 GHI ,LJKL. be four angles such that - LABC 4 ZDEF are supliments .. 1 2 +H2 + 2Гk L 3* - 522, тел. + LOEF ? LJKL. we must prove LABC ? L G H I By defination of suppliment angle. are have that m(CABC) AML DEF) = 180°. f . . MCE GHZ) + milkL) 180° By defination of conaneous angle mL DEF IMLJKL. It follows from angle that MILABC) = m(2GHI) 4 therefore ZABCM LGHI.
