Answer 1

ΔABC
ΔBDC ----{m(<A)=m(<D)=90
                {BC-latura comuna
                {[AC]=[DC]                 ===>ΔABC=ΔBDC
                  L.U.L (I.U)                         [AB]=[BD]  c.c.t.d.

b) Fie AD∩BC={M}
M∈BC

ΔABM
ΔDBM   --->{BM-latura comuna
                   {[AB]=[BD]
                   {m(<A1)=m(<D1) -din Ip   ===> ΔABM=ΔDBM
                     L.U.L                                          <B-unghi comun  ===>

===> <B1=<B2 ---> [BC-bisect < ABD
