江阴市青阳二中2016-2017学年八年级上第4周周练数学试卷含答案解析
5．下列命题中正确的是（　　）                                                                        
A．全等三角形的高相等                                                                                             
B．全等三角形的中线相等                                                                                        
C．全等三角形的角平分线相等                                                                             
D．全等三角形的对应角平分线相等                                                                  
【考点】全等三角形的性质．                                                                                
【分析】认真读题，只要甄别，其中A、B、C选项中都没有“对应”二字，都是错误的，只有D是正确的．    
【解答】解：∵A、B、C项没有“对应”                                                            
∴错误，而D有“对应”，D是正确的．                                                           
故选D．                                                                                                                         
【点评】本题考查了全等三角形的性质；注意全等三角形的性质中指的是各对应边上高，中线，角平分线相等．对性质中对应的真正理解是解答本题的关键．
