1.	Theorem 6.1 prove it please it is very important for me
Answer» Hiiii Thank you ... Animesh for being sooo kind Book mei dekho And sorry diagram nhi bna skta Given:-Tri. ABC where DE parallel BCTo proov:- AD/DB AE/ECProof :- area of tri. ADE= 1/2×base×height Area(Ade) =1/2×DB×EN Similarly area(BDE) = 1/2×DB×EN therefore area(ADE) =1/2×AD×EN/1/2×DB×EN=AD/DB - - - 1NOW, In tri. ADE and tri. DECArea(ADE) =1/2×AE×DMArea(DEC) =1/2×EC×DMTherefore, area(ADE)/area(DEC)=1/2×AE×DM/1/2×EC×DM=AE/EC - - - - - 2Tri.BDE and tri.DEC are on same base DE and between the same parallel BC and DE Area(BDE)=area(DEC) - - - 3Therefore, from equation 1,2 and 3 AD/DB=AE/EChence proved Please .....tommorow is my maths exam
