Bài 2 : Cho Δ DEF cân tại D , đường phân giác DI . Gọi n là trung điểm IF . Vẽ điểm m sao cho N là trung điểm của DM . Chứng minh rằng : a) Δ DIN = Δ MNF , MF ⊥ EF b) DF > MF c) Góc IDN > góc NDF d) D , I , K thẳng hàng ( K là trung điểm của ME )

Ai giúp em vs ạ. Em cảm ơn nhiều 😊

Cho tam giác ABC cân tại A. AM là đg phân giác. M thuộc BC a, C/m tam giác ABM = tam giác ACM b, Gọi I là trung điểm AC, trên tia đối tia IM lấy điểm E sao cho IE = I. C/m EM=EC c, Qua M kẻ đg thẳng song song AC đg thẳng này cắt tia EC tại K. C/m MC là tia phân giác của góc EMK d, Gọi H là giao điểm của MC và AI tia EH cắt MK tại F bt AM =3cm, C/m tam giác MIE >6

Mng giúp em với ạ !!! Lưu ý vẽ hình cho e luôn ạ

a. 9.15 x X + 2.85 x X = 48 b 17/5 : X =34/5: 4/3
