三、解答題

19.略 20.線段BC的長(zhǎng)為6． 21.解：（1）不存在．因?yàn)閮牲c(diǎn)之間，線段最短．因此（2）存在．線段上任意一點(diǎn)都是．

（3）不一定，也可在直線上，如圖，線段

C A B

22.解：（1）表格如下：

（2）可以得到

..n(n?1)

條線段，2n條射線.2

∠AOC=20°．

∴ ∠MON=∠MOC－∠NOC=65°－20°=45°.（2）當(dāng)銳角∠AOC的大小發(fā)生改變時(shí)，∠MON的大小不發(fā)生改變．

23.解：∵ ∠FOC=90°，∠1=40°，AB為直線，∴ ∠3+∠FOC+∠1=180°，∴ ∠3=180°－90°－40°=50°．

∵ ∠3與∠AOD互補(bǔ)，∴ ∠AOD=180°－∠3=130°.∵ OE平分∠AOD，∴ ∠2=∠AOD=65°．

24.解：（1）∵ ∠AOB是直角，∠AOC=40°，∴ ∠AOB+∠AOC=90°+40°=130°.∵ OM是∠BOC的平分線，ON是∠AOC的平分線，∵ ∠MON=∠MOC－∠NOC=2∠BOC－211

∠AOC=2（∠BOC－∠AOC）=2∠AOB，1

又∠AOB＝90°，∴∠MON=2∠AOB=45°．

∴ ∠MOC=2∠BOC=65°，∠NOC=2

25.分析：（1）有1個(gè)點(diǎn)時(shí)，內(nèi)部分割成4個(gè)三角形； 有2個(gè)點(diǎn)時(shí)，內(nèi)部分割成4+2=6（個(gè)）三角形；

那么有3個(gè)點(diǎn)時(shí)，內(nèi)部分割成4+2×2=8（個(gè)）三角形； 有4個(gè)點(diǎn)時(shí)，內(nèi)部分割成4+2×3=10（個(gè)）三角形； 有n個(gè)點(diǎn)時(shí)，內(nèi)部分割成個(gè)三角形.（2）令2n+2=2 012，求出n的值． 解：（1）填表如下：

（3）一班及格率為26%＋50%＋10%＝86%，二班及格率為32%＋44%＋12%＝88%． 21.解：（1）從折線統(tǒng)計(jì)圖可以看出各種季度用電量變化情況；

（2）冰箱用電量超過(guò)總用電量的，就是要知道部分占總體的百分比大小，4所以從扇形統(tǒng)計(jì)圖可以看出；

（3）空調(diào)的用電量就是要知道項(xiàng)目的數(shù)據(jù)，所以從條形統(tǒng)計(jì)圖可以看出． 22.解：（1）100分的同學(xué)占全班總?cè)藬?shù)的61
