八年级上册期末试卷测试卷附答案

八年级上册期末试卷测试卷附答案一、八年级数学全等三角形解答题压轴题（难） 1．（1）已知△ABC是等腰三角形，其底边是BC,点D在线段AB上，E是直线BC上一点，且∠DEC=∠DCE,若∠A等于60°（如图①）.求证：EB=AD；（2）若将（1）中的“点D在线段AB上”改为“点D在线段AB的延长线上”，其他条件不变（如图②），（1）的结论是否成立，并说明理由．【答案】（1）证明见解析（2）证明见解析【解析】试题分析：（1）作DF∥BC交AC于F，由平行线的性质得出∠ADF=∠ABC，∠AFD=∠ACB，∠FDC=∠DCE，证明△ABC是等边三角形，得出∠ABC=∠ACB=60°，证出△ADF是等边三角形，∠DFC=120°，得出AD=DF，由已知条件得出∠FDC=∠DEC，ED=CD，由AAS证明 △DBE≌△CFD，得出EB=DF，即可得出结论；（2）作DF∥BC交AC的延长线于F，同（1）证出△DBE≌△CFD，得出EB=DF，即可得出结论. 试题解析：（1）证明：如图，作DF∥BC交AC于F，则△ADF为等边三角形 ∴AD=DF，又∵∠DEC=∠DCB， ∠DEC+∠EDB=60°， ∠DCB+∠DCF=60°， ∴ ∠EDB=∠DCA ，DE=CD，在△DEB和△CDF中， 120 EBD DFC EDB DCF DE CD ，， ∠=∠=? ? ? ∠=∠ ? ?= ? ∴△DEB≌△CDF， ∴BD=DF， ∴BE=AD . (2).EB=AD成立；

理由如下：作DF∥BC交AC的延长线于F，如图所示：同（1）得：AD=DF，∠FDC=∠ECD，∠FDC=∠DEC，ED=CD，又∵∠DBE=∠DFC=60°， ∴△DBE≌△CFD（AAS）， ∴EB=DF， ∴EB=AD. 点睛：此题主要考查了三角形的综合，考查等边三角形的判定与性质，全等三角形的判定与性质，等腰三角形的判定与性质，等腰直角三角形的判定与性质，平行线的性质等知识，综合性强，有一定的难度，证明三角形全等是解决问题的关键. 2．（1）如图（1），已知：在△ABC中，∠BAC＝90°，AB=AC，直线m经过点A，BD⊥直线m, CE⊥直线m,垂足分别为点D、E.证明:DE=BD+CE. （2）如图（2），将（1）中的条件改为：在△ABC中，AB=AC，D、A、E三点都在直线m 上,并且有∠BDA=∠AEC=∠BAC=α,其中α为任意锐角或钝角.请问结论DE=BD+CE是否成立?如成立,请你给出证明;若不成立,请说明理由. （3）拓展与应用：如图（3），D、E是D、A、E三点所在直线m上的两动点（D、A、E 三点互不重合）,点F为∠BAC平分线上的一点,且△ABF和△ACF均为等边三角形，连接BD、CE,若∠BDA=∠AEC=∠BAC，试判断△DEF的形状. 【答案】（1）见解析（2）成立（3）△DEF为等边三角形【解析】解：（1）证明：∵BD⊥直线m，CE⊥直线m，∴∠BDA＝∠CEA=900． ∵∠BAC＝900，∴∠BAD+∠CAE=900． ∵∠BAD+∠ABD=900，∴∠CAE=∠ABD．又AB="AC" ，∴△ADB≌△CEA（AAS）．∴AE=BD，AD=CE． ∴DE="AE+AD=" BD+CE．（2）成立．证明如下：
