thì ai cũng chịu mà

có j thắc mắc thì mn cứ hỏi ạ, em cần trc sáng mai nhé!? ><

b: Xét ΔABD và ΔBAC có

BA chung

BD=AC

AD=BC

Do đó: ΔABD=ΔBAC

c: ta có: EA+EC=AC

EB+ED=BD

mà AC=BD

và EA=EB

nên EC=ED

9: =(x+3)^2-y^2=(x+3+y)(x+3-y)

10: =z(x+y)-2(x+y)=(x+y)(z-2)

11: =(2x+1)^2-(3y)^2

=(2x+1+3y)(2x+1-3y)

12: =(x-y)^2+4(x-y)

=(x-y)(x-y+4)

13; =(x-3y)^2-25z^2

=(x-3y-5z)(x-3y+5z)

a) Xét ΔOBH và ΔODA có 

OB=OD(gt)

\(\widehat{BOH}=\widehat{DOA}\)(hai góc đối đỉnh)

OH=OA(O là trung điểm của HA)

Do đó: ΔOBH=ΔODA(c-g-c)

Suy ra: \(\widehat{OHB}=\widehat{OAD}\)(hai góc tương ứng)

mà \(\widehat{OHB}=90^0\)(gt)

nên \(\widehat{OAD}=90^0\)

hay AH\(\perp\)AD(đpcm)

b) Xét ΔAOE vuông tại A và ΔHOC vuông tại H có

OA=OH(O là trung điểm của AH)

\(\widehat{AOE}=\widehat{HOC}\)(hai góc đối đỉnh)

Do đó: ΔAOE=ΔHOC(Cạnh góc vuông-góc nhọn kề)

Suy ra: AE=HC(hai cạnh tương ứng)(1)

Ta có: ΔAOD=ΔHOB(cmt)

nên AD=HB(Hai cạnh tương ứng)(2)

Xét ΔAHB vuông tại H và ΔAHC vuông tại H có

AB=AC(ΔABC cân tại A)

AH chung

Do đó: ΔAHB=ΔAHC(Cạnh huyền-cạnh góc vuông)

Suy ra: HB=HC(Hai cạnh tương ứng)(3)

Từ (1), (2) và (3) suy ra AD=AE

mà E,A,D thẳng hàng(gt)

nên A là trung điểm của DE

) Xét ΔOBH và ΔODA có 

OB=OD(gt)

ˆBOH=ˆDOABOH^=DOA^(hai góc đối đỉnh)

OH=OA(O là trung điểm của HA)

Do đó: ΔOBH=ΔODA(c-g-c)

Suy ra: ˆOHB=ˆOADOHB^=OAD^(hai góc tương ứng)

mà ˆOHB=900OHB^=900(gt)

nên ˆOAD=900OAD^=900

hay AH⊥⊥AD(đpcm)

b) Xét ΔAOE vuông tại A và ΔHOC vuông tại H có

OA=OH(O là trung điểm của AH)

ˆAOE=ˆHOCAOE^=HOC^(hai góc đối đỉnh)

Do đó: ΔAOE=ΔHOC(Cạnh góc vuông-góc nhọn kề)

Suy ra: AE=HC(hai cạnh tương ứng)(1)
