a) Xét tam giác AEQ và tam giác BEC có
EQ=EC
AEQ=BEC đối đỉnh
EA=EB
=> tam giác AEQ = tam giác BEC(c.g.g).
=> AQ=BC(cạnh tuognư ứng). (1)
Xét Tam giác AFP và tam giác CFB có
AF=CF
AFP=CFB đối đỉnh
FB=FP
=> tam giác AFB = tam giác CFB(c.g.c)
=> AP = BC (2)
từ (1) và (2) suy ra AP=AQ
c)
xét tam giác BEQ và tam giác AEC có
EQ=EC
BEQ=AEC đối đỉnh
EB=EA
=> tam giác BEQ = tam giác AEC(c.g.c)
=> BQE=AEC (góc tương ứng)
mà chúng ở vị trí so le trong nên BQ//AC.
xét tam giác PFC và BFA có:
FA=FC
AFB=CFP
BF=PF
=> tam giác PFC = BFA (c.g.c)
=> FAB = FCB(góc tương ứng)
mà chúng ở vị trí số le trong nên
CP//AB
