a) Tính chất tam giác cân => góc ABC= gócACB

=> góc ABM= góc ACM

b)Xét tam giác BHM và tam giác CKM có:

góc B= góc C

Góc BHM= góc CKM = 90 độ

MB=MC

=> tam giác BHM đồng dạng tam giác CKM (cạnh huyền, góc nhọn)

=>BH=CK (2canh tương ứng)

c)Xét tam giác BPC có góc P =90 độ, góc PCB = góc KCM = góc HBM(cmt)

=> góc PBC= góc IMB

=> góc IBM= góc IMB

=> tam giác IMB cân tại I
