上海市上宝中学数学全等三角形章末训练(Word版含解析) 一、八年级数学轴对称三角形填空题(难) 1.如图,P为∠AOB内一定点,M,N分别是射线OA,OB上一点,当△PMN周长最小时,∠OPM=50°,则∠AOB=___________. 【答案】40° 【解析】 【分析】 作P关于OA,OB的对称点P1,P2.连接OP1,OP2.则当M,N是P1P2与OA,OB的交点时,△PMN的周长最短,根据对称的性质可以证得:∠OP1M=∠OPM=50°,OP1=OP2=OP,根据等腰三角形的性质即可求解. 【详解】 如图:作P关于OA,OB的对称点P1,P2.连接OP1,OP2.则当M,N是P1P2与OA、OB 的交点时,△PMN的周长最短,连接P1O、P2O, ∵PP1关于OA对称, ∴∠P1OP=2∠MOP,OP1=OP,P1M=PM,∠OP1M=∠OPM=50° 同理,∠P2OP=2∠NOP,OP=OP2, ∴∠P1OP2=∠P1OP+∠P2OP=2(∠MOP+∠NOP)=2∠AOB,OP1=OP2=OP, ∴△P1OP2是等腰三角形. ∴∠OP2N=∠OP1M=50°, ∴∠P1OP2=180°-2×50°=80°, ∴∠AOB=40°, 故答案为:40° 【点睛】 本题考查了对称的性质,正确作出图形,证得△P1OP2是等腰三角形是解题的关键.

2.如图,△ABC 中,AB =AC ,∠A =30°,点D 在边AB 上,∠ACD =15°,则 AD BC =____. 【答案】2. 【解析】 【分析】 根据题意作CE ⊥AB 于E ,作DF ⊥AC 于F ,在CF 上截取一点H ,使得CH =DH ,连接DH ,并设AD =2x ,解直角三角形求出BC (用x 表示)即可解决问题. 【详解】 解:作CE ⊥AB 于E ,作DF ⊥AC 于F ,在CF 上截取一点H ,使得CH=DH ,连接DH . 设AD=2x , ∵AB=AC ,∠A=30°, ∴∠ABC=∠ACB=75°,DF 1 2 =AD=x ,AF 3=, ∵∠ACD=15°,HD=HC , ∴∠HDC=∠HCD=15°, ∴∠FHD=∠HDC+∠HCD=30°, ∴DH=HC=2x ,FH 3=, ∴3x , 在Rt △ACE 中,EC 1 2 = AC=x 3+,AE 3=3=, ∴BE=AB ﹣AE 3=﹣x , 在Rt △BCE 中,BC 22BE EC = +=2x ,
