2022-2023学年浙教版数学八上期中复习专题3 证明一、单选题(每题3分,共30分)1.()用反证法证明命题:“如图,如果AB//CD,AB//EF,那么CD//EF.”证明的第一个步骤是()A.假定CD//EF B.假定CD不平行于EFC.已知AB//EF D.假定AB不平行于EF【答案】B【知识点】反证法【解析】【解答】解:∵结论是CD∥EF,∴当用反证法证明这一命题时,第一步应该是:“假设CD和EF不平行”.故答案为:B.【分析】用反证法证明命题的第一步:通常是假设所证结论不成立,结合结论是“CD∥EF”,即可解答.2.(2022·槐荫模拟)下列各图中,已知∥1=∥2,不能证明AB∥CD的是()A.B.C.D.【答案】B【知识点】平行线的判定【解析】【解答】:A、∵∥1=∥2,∴AB∥CD,该选项不符合题意;B、由∥1=∥2,不能判断AB∥CD,该选项符合题意;C、∵∥1=∥2,∥3=∥2,∴∥1=∥3,∴AB∥CD,该选项不符合题意;D、∵∥1=∥2,∴AB∥CD,该选项不符合题意;故答案为:B.【分析】根据平行线的判定方法逐项判断即可。
3.(2022·武安模拟)定理:三角形的内角和等于180°.已知:△ABC的三个内角为∠A,∠B,∠C.求证:∠A+∠B+∠C=180°.如图1,延长BC到点D,则∠ACD=∠A+∠B(三角形的一个外角等于和它不相邻的两个内角的和).∵∠ACD+∠ACB=180°(平角的定义),∴∠A+∠B+∠ACB=180°(等量代换).如图2,过点C作DE∥AB,∵DE∥AB,∠1=∠B(两直线平行,内错角相等),∠2=∠A(两直线平行,内错角相等),又∵∠1+∠ACB+∠2=180°(平角定义),∴∠A+∠ACB+∠B=180°(等量代换).下列说法正确的是()A.证法1采用了从特殊到一般的方法证明了该定理B.证法1用合理的推理证明了该定理C.证法2还需证明其他形状的三角形,该定理的证明过程才完整D.证法2用严谨的推理证明了该定理【答案】D【知识点】推理与论证【解析】【解答】解:三角形外角和性质是建立在三角形内角和定理的基础上的,不能循环证明,故A、B都不符合题意;证法2用严谨的推理证明了该定理,故不需要分三角形的形状,故C不符合题意;D符合题意,故答案为:D.【分析】利用理论与实践结合和根据三角形的平行的性质与平角的定义可以判断作答。
