Giúp em bài này với ạ!!!
Cho tam giác ABC vuông tại A, đường cao AH. Gọi D,E là các hình chiếu của H trên AB và AC. I là trung điểm của BH, K là trung điểm của HC. CMR:
a) DI//EK
b) Đường thẳng qua A vuông góc với DE cắt BC tại M. CMR: M là trung điểm của BC
c)Nếu M là trung điểm của BC thì AM có vuông góc với DE không? Tại sao?
Mọi người bớt chút tgian giải giúp mình với ạ!!
