如圖，長方形ABCD沿著AE折疊，使D點(diǎn)落在BC邊上的F點(diǎn)處，如果∠BAF=50°，
則∠AEF的度數(shù)為（   ）

A．50°

B．65°

C．75°

D．70°

.如圖,△ABC中,點(diǎn)D、E、F分別在三邊上,E為AC中點(diǎn),AD、BE、CF 交于一點(diǎn)BD=2DC,S△GEC=3,S△GDC=4,則△ABC的面積是(   )
­  A.25­        B.30­       C.35­       D.40

小明的運(yùn)動(dòng)衣上的號(hào)碼在鏡子中的字樣為“108”，那么他的運(yùn)動(dòng)衣上的實(shí)際號(hào)碼是      

如圖，A、B、C為三個(gè)村莊，村莊C剛好在AB的中垂線上，則AC     BC（填“＞”、“＜”或“＝”）．

如圖，將△ABC（其中∠ABC = 60°，∠C = 90°）繞點(diǎn)B按順時(shí)針轉(zhuǎn)動(dòng)一個(gè)小于180°的角度到△的位置，使得點(diǎn)A，B，在同一條直線上，那么旋轉(zhuǎn)角度的大小等于 
         °．

△ABC中，AB=9，BC=2，周長是偶數(shù)，則AC=      

四個(gè)圖形分別是正三角形、等腰梯形、長方形、正五邊形，它們?nèi)�部是軸對(duì)稱圖形，其中對(duì)稱軸的條數(shù)最少的圖形是_____．

我們知道：有兩條邊相等的三角形叫做等腰三角形．類似地，我們定義：至少有一組對(duì)邊相等的四邊形叫做等對(duì)邊四邊形．

【小題1】請寫出一個(gè)你學(xué)過的四邊形中是等對(duì)邊四邊形的圖形的名稱；
【小題2】在中，如果是銳角，點(diǎn)分別在上，且．猜想圖中哪個(gè)四邊形是等對(duì)邊四邊形，并證明你的結(jié)論．

Rescue workers at the San Jose gold and copper mine in northern Chile had reason to sing this week．A small hole drilled into the earth became a passage（通道） to freedom for thirty-three trapped miners．They spent sixty-nine days underground．"Never have people been trapped for so long so deeply," says a doctor at NASA, the American space agency, which helped in the rescue．
But the chief medical officer for the miners said most are in good enough health to leave the hospital within a day or so．The first three were released from the hospital Thursday night．
For much of the day the miners relaxed with Chilean President Sebastian Pinera．The thirty-two Chileans and one Bolivian still wore special sunglasses to protect their eyes．
A  partial mine collapse（坍塌） on 5^th of August trapped them more than half a kilometer underground．They had to stretch a two-day food supply．For two weeks no one knew if they were alive or dead．
Later, they received supplies（供給） and a video link lowered through drill holes．That link was how Ariel Ticona watched his wife give birth to their daughter．
The miners have apparently agreed to share the money they earn from selling their story．
They have already received gifts of money and travel offers．Edison Pena has been invited to the New York City Marathon and to Graceland, the home of Elvis Presley in Memphis, Tennessee．Mr．Pena described how he ran in the mine tunnels to ease the stress．And he led the miners in singing Elvis songs．
The first miner rescued on Wednesday was Florencio Avalos．The second was Mario Sepulveda, who talked about how the experience tested his faith．He said: "I was with God and I was with the devil, they fought me, but God won．He took me by my best hand, the hand of God．"
The last miner up was Luis Urzua．He was the shift leader when his crew became trapped．
Rescuers used a metal cage to pull the miners to safety in less than twenty-four hours -- faster than expected．The rescue capsule was a half-meter wide and known as the Phoenix．
