冀教版八年级上册数学第13章 全等三角形 全等图形

冀教版八年级上册数学第13章 全等三角形  全等图形

9.(河北石家庄月考)如图,△ABD≌△BAC,B,C 和 A,D 分 别是对应顶点.如果 AB=4 cm,BD=3 cm,AD=5 cm,那 么 BC 的长是( A ) A.5 cm B.4 cm C.3 cm D.无法确定
10.如图,直角三角形 ABC 沿直角边 BC 所在的直线向右平移 得到△DEF,下列结论不.一.定.成立的是( D )
(2)当△ABD 满足什么条件时,BD∥CE?并说明理由.
【思路点拨】要使 BD∥CE,则需∠BDE=∠CEA,而由 △BAD≌△ACE 可知∠ADB=∠CEA,由此可得结果. 【点拨】对于探究条件的题目,可以猜想出条件后,由条件推出 题目的结论,也可以将题目中的结论当作条件,这样推出的结论 即为题目要探究的条件.
(2)求 AB 的长. 解:∵△ABC≌△FED,∴AB=EF. ∴AB-EB=EF-EB. ∴AE=BF. ∵AF=8,BE=2,∴AE+BF=8-2=6. ∴AE=3. ∴AB=AE+BE=3+2=5.
15.如图,已知△ABC≌△DBE,点 D 在 AC 上,BC 与 DE 交 于点 P.
(1)若∠ABE=160°,∠DBC=30°,求∠CBE 的度数;
16.如图,把两个大小完全相同的长方形堆成“L”形. (1)指出图中的全等四边形和全等三角形;
解:四边形 ABCD≌四边形 AEFG, △AFG≌△FAE≌△ACD≌△CAB.
(2)判断△AFC 的形状. 解:因为△FAE≌△ACD,所以 AF=AC,∠FAE=∠ACD. 因为四边形 ABCD 是长方形,所以∠ADC=90°. 所以∠ACD+∠CAD=90°. 所以∠FAE+∠CAD=90°,即∠FAC=90°. 所以△AFC 是等腰直角三角形.
17.如图,A,D,E 三点在同一直线上,且△BAD≌△ACE. (1)求证:BD=DE+CE;

冀教版数学八年级上册《17.4 直角三角形全等的判定》教学设计1

冀教版数学八年级上册《17.4 直角三角形全等的判定》教学设计1

冀教版数学八年级上册《17.4 直角三角形全等的判定》教学设计1一. 教材分析冀教版数学八年级上册《17.4 直角三角形全等的判定》是直角三角形全等知识的一部分。

本节课的主要内容是让学生掌握HL(Hypotenuse-Leg)判定法,即直角三角形中,如果两个直角三角形的斜边和一条直角边分别相等,那么这两个直角三角形全等。

学生通过本节课的学习,可以进一步理解全等形的概念,提高解决几何问题的能力。

二. 学情分析学生在学习本节课之前,已经学习了全等形、三角形的全等条件(SAS、ASA、AAS)以及直角三角形的性质。

但部分学生对全等形的概念理解不深,对直角三角形全等的判定方法辨识不清,运用不灵活。

因此,在教学过程中,教师需要关注学生的知识基础,引导学生理解全等形的概念,并通过实例分析,让学生掌握直角三角形全等的判定方法。

三. 教学目标1.知识与技能目标:让学生掌握HL判定法,能运用HL判定法判断两个直角三角形是否全等。

2.过程与方法目标:通过观察、分析、归纳,培养学生的逻辑思维能力和空间想象能力。

3.情感态度与价值观目标:激发学生学习数学的兴趣,培养学生的团队协作精神,使学生在解决实际问题中体验到数学的价值。

四. 教学重难点1.教学重点:掌握HL判定法,能运用HL判定法判断两个直角三角形是否全等。

2.教学难点:对HL判定法的理解与应用,能灵活运用HL判定法解决实际问题。

五. 教学方法采用问题驱动法、案例分析法、小组合作法、引导发现法等教学方法。

通过生动有趣的实例,引导学生观察、分析、归纳直角三角形全等的判定方法,激发学生的学习兴趣,培养学生的逻辑思维能力和空间想象能力。

六. 教学准备1.准备相关的教学案例和图片,用于引导学生观察和分析。

2.准备PPT,展示教学内容和实例分析。

3.准备练习题,用于巩固所学知识。

七. 教学过程1.导入(5分钟)教师通过一个实际问题引入本节课的主题:在直角三角形ABC中,AB是斜边,AC是直角边,如果在另一个直角三角形DEF中,DF是斜边,DE是直角边,并且AB=DF,AC=DE,那么这两个直角三角形全等吗?2.呈现(10分钟)教师通过PPT呈现直角三角形全等的判定方法(HL判定法),并用实例进行解释和演示。

AGiving directions in different placesIf you ask people of different countries “Could you tell me the way to the post office? You will get different answers.In Japan, people use landmarks (路标) instead of street names. For example, Japanese will say to travelers,“Go straight do wn to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop. ”In Kansas, America, there are no towns or buildings within (在……之内) miles. So instead of landmarks, people will tell you directions and d istance. For example, people will say, “Go north two miles(英里). Turn east, and then go another mile.”People in Greece sometimes do not even try to give directions. They will often say, “Follow me.” Then he or she will take you through the streets of the city to the post office.Sometimes if a person doesn’t know the answer to your question, he or she, like a New Yorker, might say, “Sorry, I have no idea.” But in Yucatan, Mexico, no one answers “I don’t know.” People there think “I don’t know” is not poli te.
