参考答案

°

14.(1,2) 15.同位角相等 两直线平行 16.115° 17.11 18.(2,0)或(7,-5)

19.原式=3-1

2-(-0.5)+4-6=1.

20.(1)我是最棒的. (2)努力就能行. (3)明天会更好.

21.证明:∵∠1=∠2(已知),∠1=∠5(对顶角相等),∴∠2=∠5(等量代换).

∴l1∥l2(同位角相等,两直线平行).

∴∠6+∠7=180°(两直线平行,同旁内角互补).

又∵∠4=∠6(对顶角相等),∠3=∠7(对顶角相等),

∴∠3+∠4=∠6+∠7(等量代换).

∴∠3+∠4=180°.

22.把d=32,f=2代入

v=16

千米/时).

∵128>80,

∴肇事汽车当时超出了规定的速度.

23.证明:∵∠B=∠ADE,∴DE∥BC.∴∠EDC=∠DCF.

又∵∠EDC=∠GFB,∴∠DCF=∠GFB.∴CD∥GF.∴∠CDG=∠FGB.

又∵GF⊥AB,∴∠CDG=∠FGB=90°.∴CD⊥AB.

24.(1)坐标系图略.

(2)各点的坐标分别为:B(5,2),C(-5,2),D(-9,0),E(-5,-2),F(5,-2).

(3)EF∥BC,DE∥AB,DC∥AF. 25.(1)E(4,1),F(0,-2),G(5,-3).

(2)S△EFG=4³5-3³4³1

2-1³5³1

2-4³1³1

2=20-6-2.5-2=9.5.

26.(1)∠2=∠1+∠3.过点E作EF∥AB.

∵AB∥CD,∴AB∥CD∥EF.∴∠1=∠BEF,∠3=∠CEF.

∴∠1+∠3=∠BEF+∠CEF=∠BEC.即∠1+∠3=∠2.

(2)∠2+∠4=∠1+∠3+∠5.

分别过E,G,M作EF∥AB,GH∥AB,MN∥AB.

∵AB∥CD,∴AB∥CD∥EF∥HG∥MN.

∴∠1=∠BEF,∠FEG=∠EGH,∠HGM=∠GMN,∠NMC=∠5.

∴∠2+∠4=∠BEF+∠FEG+∠GMN+∠NMC=∠1+∠EGH+∠5,

即∠2+∠4=∠1+∠3+∠5.

(3)∠2+∠4+∠6=∠1+∠3+∠5+∠7. 分别过点E,G,M,K,P作EF∥AB,GH∥AB,MN∥AB,LK∥AB,PQ∥AB.

∵AB∥CD,∴AB∥CD∥EF∥GH∥MN∥LK∥PQ.

∴∠1=∠BEF,∠FEG=∠EGH,∠HGM=∠GMN,∠KMN=∠LKM,∠LKP=∠KPQ,∠QPD=∠7.

∴∠2+∠4+∠6=∠1+∠3+∠5+∠7.

结论:开口朝左的所有角度之和等于开口朝右的所有角度之和.

be much cheaper and easier. And many people will go to other countries for holiday.

There will be changes in our food, too. Because more and more people know the{余干沙港中学随笔}.

importance of healthy diet, maybe no one will eat meat. Instead they will eat more

vegetables and fruit. So people will be healthier. Work in the future will be

yesterday was the worst day. I bought some music CDs, and put them in my bag so that

you wouldn't see them. I told you I had to do my homework first. I know it was wrong

to lie (说谎) to you, but you told me that Dad would talk to me later. Mom, I didn't

Many students have fun with their school life. But many Japanese students are unhappy. They have lots of pressure from their family. Most of Japanese students must study hard at school to please their parents and for future. So it’s tiring and boring for some students. Japanese students always try their best in school, but sometimes they may fail exams and make their parents lose hope for them. The students may have bigger pressure from both family and the school. So they finally don’t get interested in their schoolwork. In this way, more pressure and problems are waiting for them. That’s really a terrible thing. To a report, most Japanese parents would like to send their children to different schools on weekends, but it only helps kids to get good grades. They never mind the students’ healthy development (成长). For example, many school students said they don’t know how to get on well with and how to take care of others. That’s bad for kids’ whole development. In Japan,many schools usually own their strict rules from hair to clothes. So Japanese students live with great pressure both in school and at home.

A. their parents give them too much pressure

B. they have to work hard on weekends schools

Many parents make their children do chores around the house. For some families, teaching children what to do and how to do chores is easy. But in other families, getting children to do some housework can be a very big problem.

It is a good idea for parents to teach their children at an early age that all family members must work together to make the house clean, and each person must do

20.(1)我是最棒的. (2)努力就能行. (3)明天会更好.

21.证明:∵∠1=∠2(已知),∠1=∠5(对顶角相等),∴∠2=∠5(等量代换).

∴l1∥l2(同位角相等,两直线平行).

∴∠6+∠7=180°(两直线平行,同旁内角互补).

又∵∠4=∠6(对顶角相等),∠3=∠7(对顶角相等),

∴∠3+∠4=∠6+∠7(等量代换).

∴∠3+∠4=180°.

22.把d=32,f=2代入

v=16

千米/时).

∵128>80,

∴肇事汽车当时超出了规定的速度.

23.证明:∵∠B=∠ADE,∴DE∥BC.∴∠EDC=∠DCF.

又∵∠EDC=∠GFB,∴∠DCF=∠GFB.∴CD∥GF.∴∠CDG=∠FGB.

(2)∠2+∠4=∠1+∠3+∠5.

分别过E,G,M作EF∥AB,GH∥AB,MN∥AB.

∵AB∥CD,∴AB∥CD∥EF∥HG∥MN.

∴∠1=∠BEF,∠FEG=∠EGH,∠HGM=∠GMN,∠NMC=∠5.

∴∠2+∠4=∠BEF+∠FEG+∠GMN+∠NMC=∠1+∠EGH+∠5,

即∠2+∠4=∠1+∠3+∠5.

(3)∠2+∠4+∠6=∠1+∠3+∠5+∠7. 分别过点E,G,M,K,P作EF∥AB,GH∥AB,MN∥AB,LK∥AB,PQ∥AB.
