∆ cân ABC (AB = AC). Từ trung điểm M của BC vẽ ME vuông góc AC; MF vuông góc AC. Chứng minh rằng

a) ∆BEM = ∆CFM

b) AE = AF

c) AM là phân giác của góc EMF

d) So sánh MC và ME

ΔABC cân tại A, trung tuyến AM. Từ M kẻ ME⊥AB tại E, kẻ MF⊥AC tại F.

a) chứng minh: ΔBEM=ΔCFM

b) chứng minh AM là trung trực của EF.

c) Từ B kẻ đường thẳng vuông góc với AB tại B, từ C kẻ đường thẳng vuông góc với AC tại C, hai đường thẳng này cắt nhau tại D. Chứng minh rằng ba điểm A,M,D thẳng hàng
