Question

VA ROG REPEDEE PLSsssss

Answer 1

a) dacă ABCD - paralelogram => BC||AD și dacă E€ BC => EC||AD

EC = BC - BE = 12-8=4

ABCD - paralelogram => AD=BC

AB=CD

conform TFA in AFD => EFC ≈ AFD => EF/AF=FC/FD=EC/AD => EF /AF=FC/FD = 1/3 => EF/AF = 1/3

EF/AF = 1/3 => AE/EF = 3-1/1 = 2

b) CD||AB => FD || AB => TFA in BGA => BGA ≈ DGF => BG/DG = GA/GF =BA/DF => AG/GF =AB/DF

spor!
