Lana told Ben that she wasn’t mad at Marcia anymore，and that she would go to Marcia’s house on Friday night. However，Marcia called everyone and told them that she wasn’t going to have the party.

本是同根生，相煎何太急.（曹植）——《七步詩》
誰知盤中餐，粒粒皆辛苦.（李紳）——《憫農》或《鋤禾》
野火燒不盡，春風吹又生.（白居易）——《草》或《賦得古原草送別》
誰言寸草心，報得三春暉.（孟郊）——《遊子吟》

如圖，已知點F是正方形ABCD的邊BC的中點，CG平分∠DCE，GF⊥AF.求證：AF=FG.

證明：取AB的中點M，連接FM.∵點F是正方形ABCD的邊BC的中點，∴BF=BM，∴∠BMF=45°，∴∠AMF=135°.∵CG平分∠DCE，∴∠GCE=45°，∴∠FCG=135°，∴∠AMF=∠FCG.∵∠B=90°，∴∠FAM=90°-∠AFB，∵GF⊥AF，∴…

3.2/1.25簡算，

原式
=3,2÷（10÷8）
=3.2×8÷10
=25.6÷10
=2.56

二次根式的計算…怎麼算的，都要一個個開出來？
（-√5）^2-√16+√（-2）^2=
√（4/7-1/2）^2+√（4/7-1）^2=
√（1-√2）^2+√（√2+1）^2=

1 5-4+2=3
2 1/14+3/7=7/14=1/2
3根號2-1+根號2+1=2根號2
根號和平管道互逆的運算平方在裡面只是保證裡面變成正的所以裡面原來是什麼出來根號就還是什麼如果是負的就直接變成正的

如圖12在梯形ABCD中，上底長是下底長的一半，E是CD腰的中點，F點是BE線段的中點.
陰影部分是梯形面積的百分之幾？

六分之一.我也是藍天滴，翠竹分校Christine班的

已知多項式mx的平方+2xy-x與3x的平方-2nxy+3y（m，n為常數項）的差不含二次項，求n的m方的值？

原式=（mx）^2 +2xy-x-（3x）^2+2nxy-3y
=（m^2-9）x^2+（2+2n）xy-x-3y
由題意：m^2-9=0，2+2n=0
所以m=3或-3，n=-1
n^m=-1

一個圓形木板裁成一個最大的正方形，裁得木板對角線長2分米，求正方形的面積.

正方形兩對角線相互平分且垂直，對角線將正方形分為兩個三角形，可求三角形面積承2，對角線長2分米，三角形底就是2，高是1，那正方形面積就是2＊1/2＊2＊1＝2，

如圖，行四邊形ABCD的對角線AC，D相交於點O，F⊥BD於O，別交AD，C於E，且AE=EO=1/2BF，證明四邊形ABCD為矩形.

在三角形AEO與三角形CFO中：OA=OC（平行四邊形對角線相互平分）；角EAO=角FCO（兩直線平行同位角相等）；角AOE=角COF（對頂角相等）；所以三角形EAO與三角形CFO全等.所以OE=OF=AE=1/2BC.所以OF=1/2BF.又OF⊥BD於O；所以角OAF=30度；由三角形AEO與三角形CFO全等可知OF=FC所以角FCO=角FOC=30度.所以OB=OC；所以AC=BD.所以四邊形ABCD為矩形（對角線相等的平行四邊形是矩形）
