2.解:
3.⑴∠C=45°分⑵∠C=∠APC-∠A(证明略)⑶不成立,新的相等关系为∠C=∠APC+∠A(证明略)
4.解:(1)∵(a﹣3)2+|b+4|=0,∴a﹣3=0,b+4=0,∴a=3,b=﹣4,∴A(3,0),B(0,﹣4),∴OA=3,OB=4,∵S四边形AOBC=16.∴0.5(OA+BC)×OB=16,∴0.5(3+BC)×4=16,∴BC=5,∵C是第四象限一点,CB⊥y轴,∴C(5,﹣4)(2)如图,延长CA,∵AF是∠CAE的角平分线,∴∠CAF=0.5∠CAE,∵∠CAE=∠OAG,∴∠CAF=0.5∠OAG,∵AD⊥AC,∴∠DAO+∠OAG=∠PAD+∠PAG=90°,∵∠AOD=90°,∴∠DAO+∠ADO=90°,∴∠ADO=∠OAG,∴∠CAF=0.5∠ADO,∵DP是∠ODA的角平分线∴∠ADO=2∠ADP,∴∠CAF=∠ADP,∵∠CAF=∠PAG,∴∠PAG=∠ADP,∴∠APD=180°﹣(∠ADP+∠PAD)=180°﹣(∠PAG+∠PAD)=180°﹣90°=90° 即:∠APD=90°
(3)不变,∠ANM=45°理由:如图,∵∠AOD=90°,∴∠ADO+∠DAO=90°,∵DM⊥AD,∴∠ADO+∠BDM=90°,∴∠DAO=∠BDM,∵NA是∠OAD的平分线,∴∠DAN=0.5∠DAO=0.5∠BDM,∵CB⊥y轴,∴∠BDM+∠BMD=90°,∴∠DAN=0.5(90°﹣∠BMD),∵MN是∠BMD的角平分线,∴∠DMN=0.5∠BMD,∴∠DAN+∠DMN=0.5(90°﹣∠BMD)+0.5∠BMD=45° 在△DAM中,∠ADM=90°,∴∠DAM+∠DMA=90°,在△AMN中,∠ANM=180°﹣(∠NAM+∠NMA)
=180°﹣(∠DAN+∠DAM+∠DMN+∠DMA)=180°﹣[(∠DAN+DMN)+(∠DAM+∠DMA)] =180°﹣(45°+90°)=45°,∴D点在运动过程中,∠N的大小不变,求出其值为45° 5.略 6.解:
(1)120°;∠CBN(2)∵AM∥BN,∴∠ABN+∠A=180°,∴∠ABN=180°-60°=120°,∴∠ABP+∠PBN=120°,∵BC平分∠ABP,BD平分∠PBN,∴∠ABP=2∠CBP,∠PBN=2∠DBP,∴2∠CBP+2∠DBP=120°,∴∠CBD=∠CBP+∠DBP=60°;(3)不变,∠APB:∠ADB=2:1. ∵AM∥BN,∴∠APB=∠PBN,∠ADB=∠DBN,∵BD平分∠PBN,∴∠PBN=2∠DBN,∴∠APB:∠ADB=2:1;(4)∵AM∥BN,∴∠ACB=∠CBN,当∠ACB=∠ABD时,则有∠CBN=∠ABD,∴∠ABC+∠CBD=∠CBD+∠DBN,∴∠ABC=∠DBN,由(1)可知∠ABN=120°,∠CBD=60°,∴∠ABC+∠DBN=60°,∴∠ABC=30°.
7.解:(1)∵ED∥BC,∴∠B=∠EAD,∠C=∠DAE,故答案为:∠EAD,∠DAE;
(2)过C作CF∥AB,∵AB∥DE,∴CF∥DE,∴∠D=∠FCD,∵CF∥AB,∴∠B=∠BCF,∵∠BCF+∠BCD+∠DCF=360°,∴∠B+∠BCD+∠D=360°,(3)A.如图2,过点E作EF∥AB,∵AB∥CD,∴AB∥CD∥EF,∴∠ABE=∠BEF,∠CDE=∠DEF,∵BE平分∠ABC,DE平分∠ADC,∠ABC=60°,∠ADC=70°,∴∠ABE=∠ABC=30°,∠CDE=∠ADC=35°,∴∠BED=∠BEF+∠DEF=30°+35°=65°;故答案为:65; B、如图3,过点E作EF∥AB,∵BE平分∠ABC,DE平分∠ADC,∠ABC=n°,∠ADC=70° ∴∠ABE=∠ABC=n°,∠CDE=∠ADC=35°
∵AB∥CD,∴AB∥CD∥EF,∴∠BEF=180°﹣∠ABE=180°﹣n°,∠CDE=∠DEF=35°,∴∠BED=∠BEF+∠DEF=180°﹣n°+35°=215°﹣n°.故答案为:215°﹣n.

10.解:
11.解:
12.解:(1)根据题意,可得三角形OAB沿x轴负方向平移3个单位得到三角形DEC,∵点A的坐标是(1,0),∴点E的坐标是(-2,0);故答案为:(-2,0);(2)①∵点C的坐标为(-3,2).∴BC=3,CD=2,∵点P的横坐标与纵坐标互为相反数;∴点P在线段BC上,∴PB=CD,即t=2; ∴当t=2秒时,点P的横坐标与纵坐标互为相反数;故答案为:2; ②当点P在线段BC上时,点P的坐标(-t,2),当点P在线段CD上时,点P的坐标(-3,5-t);
③能确定,如图,过P作PE∥BC交AB于E,则PE∥AD,∴∠1=∠CBP=x°,∠2=∠DAP=y°,∴∠BPA=∠1+∠2=x°+y°=z°,∴z=x+y.
13.解:
14.解:(1)∵点A(0,8),∴AO=8,∵△AOB绕点A逆时针旋转90°得△ACD,∴AC=AO=8,∠OAC=90°,∴C(8,8),故答案为:(8,8);
(2)①延长DC交x轴于点E,∵点B(m,0),∴OB=m,∵△AOB绕点A逆时针旋转90°得△ACD,∴DC=OB=m,∠ACD=∠AOB=90°,∠OAC=90°,∴∠ACE=90°,∴四边形OACE是矩形,∴DE⊥x主,OE=AC=8,分三种情况:
a、当点B在线段OE的延长线上时,如图1所示:
则BE=OB﹣OE=m﹣8,∴S=0.5DC•BE=0.5m(m﹣8),即S=0.5m2﹣4m(m>8); b、当点B在线段OE上(点B不与O,E重合)时,如图2所示:
2则BE=OE﹣OB=8﹣m,∴S=0.5DC•BE=0.5m(8﹣m),即S=﹣0.5m+4m(0<m<8); c、当点B与E重合时,即m=8,△BCD不存在;
综上所述,S=0.5m2﹣4m(m>8),或S=﹣0.5m2+4m(0<m<8); ②当S=6,m>8时,0.5m﹣4m=6,解得:m=4±222
(负值舍去),∴m=4+2;
当S=6,0<m<8时,﹣0.5m+4m=6,解得:m=2或m=6,∴点B的坐标为(4+2,0)或(2,0)或(6,0).15.
