题目

.如图所示，已知△ABC和△BDE都是等边三角形，下列结论：①AE=CD；②BF=BG；③BH平分∠AHD；④∠AHC=60°；⑤△BFG是等边三角形；⑥FG∥AD，其中正确的有（ ）A. 3个 B. 4个 C. 5个 D. 6个 答案：【答案】D【解析】∵△ABC与△BDE为等边三角形，∴AB=BC，BD=BE，∠ABC=∠DBE=60°，∴∠ABE=∠CBD，即AB=BC，BD=BE，∠ABE=∠CBD∴△ABE≌△CBD，∴AE=CD，∠BDC=∠AEB，又∵∠DBG=∠FBE=60°，∴△BGD≌△BFE，∴BG=BF，∠BFG=∠BGF=60°，∴△BFG是等边三角形，∴FG∥AD，∵BF=BG，AB=BC，∠ABF=∠CBG=60°，∴△ABF≌△CGB，∴∠BAF=∠— Could you give me a ride to the railway station?
