a)

Xét \(\Delta AOD\) và \(\Delta COB\) có: \(\left\{{}\begin{matrix}OA=OC\left(gt\right)\\\widehat{O}:chung\\OB=OD\left(gt\right)\end{matrix}\right.\)

\(\Rightarrow\Delta AOD=\Delta COB\left(c.g.c\right)\)

\(\Rightarrow AD=BC\left(\text{2 cạnh tương ứng}\right)\left(\text{đpcm}\right)\)

b) 

Nối A với C

Ta có: \(\left\{{}\begin{matrix}OA=OC\\OB=OD\end{matrix}\right.\left(gt\right)\Rightarrow OA-OB=OC-OD\)

Hay \(AB=CD\)

Xét \(\Delta ABC\) và \(\Delta CDA\) có: \(\left\{{}\begin{matrix}AB=CD\left(cmt\right)\\AC:chung\\AD=BC\left(cmt\right)\end{matrix}\right.\)

\(\Rightarrow\Delta ABC=\Delta DCA\left(c.c.c\right)\)

\(\Rightarrow\widehat{ABC}=\widehat{CDA}\left(\text{2 góc tương ứng}\right)\)

Vì \(\Delta AOD=\Delta COB\left(cmt\right)\Rightarrow\widehat{A}=\widehat{C}\left(\text{2 góc tương ứng}\right)\)

Xét \(\Delta ABE\) và \(\Delta CDE\) có: \(\left\{{}\begin{matrix}\widehat{ABC}=\widehat{CDA}\left(cmt\right)\\AB=CD\left(cmt\right)\\\widehat{A}=\widehat{C}\left(cmt\right)\end{matrix}\right.\)

\(\Rightarrow\Delta ABE=\Delta CDE\left(g.c.g\right)\left(\text{đpcm}\right)\)

c) Vì \(\Delta ABE=\Delta CDE\left(cmt\right)\Rightarrow AE=CE\left(\text{2 cạnh tương ứng}\right)\)

Xét \(\Delta AOE\) và \(\Delta COE\) có: \(\left\{{}\begin{matrix}OA=OC\left(gt\right)\\\widehat{A}=\widehat{C}\left(cmt\right)\\AE=CE\left(cmt\right)\end{matrix}\right.\)

\(\Rightarrow\Delta AOE=\Delta COE\left(c.g.c\right)\\ \Rightarrow\widehat{AOE}=\widehat{COE}\left(\text{2 góc tương ứng}\right)\)

`=> OE` là phân giác của \(\widehat{xOy}\) (đpcm)
