（等量代换）所以AE∥BF（同位角相等，两直线平行）得∠4=∠F （两直线平行，同位角相等）因为∠A=∠F（已知）得∠4=∠A所以DF∥AC（内错角相等，两直线平行）所以∠C=∠D两直线平行，内错角相等（两直线平行，内错角相等）【解答】证明：∵∠1=∠2（已知），∠1=∠3（对顶角相等），∴∠2=∠3（等量代换），∴AE∥BF （同位角相等，两直线平行），∴∠4=∠F（两直线平行，同位角相等），∵∠A=∠F（已知），∴∠4=∠A，∴DF∥AC，（内错角相等，两直线平行），∴∠C=∠D （两直线平行，内错角相等），故答案为：对顶角相等，等量代换，BF，同位角相等，两直线平行，两直线平行，同位角相等，∠A=∠F，DF，AC，两直线平行，内错角相等．27．（8分）已知：AD⊥BC，垂足为D，EG⊥BC，垂足为点G，EG交AB于点F，且AD平分∠BAC，试说明∠E=∠AFE的理由．【解答】解：理由是：∵AD⊥BC，EG⊥BC（已知），∴∠ADC=∠EGD=90°（垂直的意义），∴EG∥AD（同位角相等，两直线平行），∴∠E=∠CAD（两直线平行，同位角相等），∠AFE=∠BAD（两直线平行，内错角相等），∵AD平分∠BAC（已知），∴∠BAD=∠CAD（角平分线定义），∴∠E=∠AFE（等量代换）．28．（10分）（1）如图α示，AB∥CD，且点E在射线AB与CD之间，请说明∠AEC=∠A+∠C的理由．（2）现在如图b示，仍有AB∥CD，但点E在AB与CD的上方，①请尝试探索∠1，∠2，∠E三者的数量关系．②请说明理由．【解答】解：（1）过点E作EF∥AB；∴∠A=∠AEF（两直线平行，内错角相等）∵AB∥CD（已知）∴EF∥CD（平行的传递性），∴∠FEC=∠C（两直线平行，内错角相等），∵∠AEC=∠AEF+∠FEC（图上可知）∴∠AEC=∠A+∠C（等量代换）；（2）∠1+∠2﹣∠E=180°，说理如下：过点E作EF∥AB∴∠AEF+∠1=180°（两直线平行，同旁内角互补），∵AB∥CD（已知）∴EF∥CD（平行的传递性），∴∠FEC=∠2（两直线平行，内错角相等），即∠CEA+∠AEF=∠2∴∠AEF=∠2﹣∠CEA（等式性质）∴∠2﹣∠CEA+∠1=180°（等量代换），即∠1+∠2﹣∠AEC=180°。
