Bạn tự vẽ hình nha!

b.Vì △ABD = △ACE (cmt)

Nên: AD=AE (cạnh tương ứng)

=> △AED cân tại A

Do đó: AED = (180 - BAC)/2 (1)

Vì △ABC cân tại A

Nên: ABC = (180 - BAC)/2 (2)

Từ (1) và (2) suy ra: AED = ABC

Hai góc này ở vị trí đồng vị

Nên: DE // BC (đpcm)

c. Gọi I là giao điểm của AH và BC

Xét △AHE và △AHD có:

AH chung

AEH = ADH =90

AE=AD (cmt)

Nên: △AHE=△AHD (ch.cgv)

=> HAE=HAD (góc tương ứng)

Hay: BAI=CAI

Xét △ABI và △ACI có:

AB=AC (gt)

BAI=CAI (cmt)

AI chung

Nên: △ABI =△ACI (c.g.c)

=> AIB=AIC (góc tương ứng)

Mà: AIB + AIC = 180 (kề bù)

AIB + AIB = 180

2AIB = 180

AIB = 90

Do đó: AI ⊥ BC

Hay : AH ⊥ BC (đpcm)

Do mình hơi gà mờ nên bạn thông cảm về mấy cái kí hiệu như góc và độ nha!

1.Nobody in my family is older than my grandmother.

2.We started learning English when we were in grade 3.

3.There is noise pollution.People and animals have hearing problems.

Cho △ABC, M là trung điểm AC. Trên tia đối BM lấy D sao cho MD=MB. Trên tia đối của BC, lấy E sao cho BE=BC. Gọi I là giao điểm AD và DE. C/m IA=IB

CÁC BẠN GIÚP MÌNH VS Ạ!

Cho △ABC có góc A=90, phân giác góc B cắt AC tại D và cắt đường thảng vẽ từ C vuông góc vs AC tại E

a. So sánh AB và CE

b. Kẻ DH ⊥ BC. So sánh AD và CD
