21.AR+AD=AC.证明：因为∠DCE=∠BC=∠A=90P,所以∠AC)+∠ACE=909=∠E+∠AC.所以∠AC)=∠∠A=∠EBC,在△ACD和△BEC中，{∠ACD=∠E,DC=CE.听以△ACD≌△BEC(AAS).所以AD=BC.所以AB+AD=AB+BC=AC22.(1)因为∠A+∠ABC+∠C+∠1DC=360°，∠A=∠C=90P.所以∠ABG+∠ADC=360°-90°-90°=180°.因为BE,DF分别分∠ABC和∠ADC,所以∠ABC=2∠1，∠ADG=2∠2.所以2∠1+2∠2=180°.所以21+∠2=号×180°=909(2)设多边形的边数为n,则(n-2)×180°=2×360°+360解得n=8.所以(8-2)×180°÷8=135°，即这个多边形的每个内角都是135°23.（1)因为ADLBC,BD=ED,所以AB=AE.所以∠D1E=2∠BME=20°，∠AED=90°-∠DAE=70°.因为EF垂H分AC,所以AE=CE.所以∠EAC=∠C,且∠AED=∠EAC+∠C=2∠C=70°.所以∠C=35.(2)因为△ABC的周长为18cm,AC=6em,听以AB+BG=18-6=12(cm).因为AE=CE.所以△ABB的周长=AB+B+AE=AH+BE EC=AB+BC=12(cm).24.（1)因为△ABC为等边三角形，所以∠ABG=60°.因为D为AC的中点，所以DB分∠ABC所以∠DC=30因为∠PDQ=120°，所以∠P=180°-120°-30°=30所以∠DBC=∠P.所以DB=DP(2)过点D作DBC交AB于点I.因为△ABC是等边三角形，AC=8,D是AC的中点，所以AD=CD=4,∠B=∠C=∠A=60°，BC=AC=8.因为DI∥BC,所以∠ADH=∠C=60°，∠AHD=∠B=60P.所以∠ADH=∠AHD=∠A=60所以△A)/是等边三角形，所以AD=HD=AH=4.所以IID=CD=BI=4.因为∠Q0P=∠H1DG=120P,所以∠QDH=∠PDC∠(OHDH=∠PDC,在△QDI和△PD中，HD=CD,∠(01110=∠C所以△ODH≌△PDC(ASA).所以HQ=CP:所以BQ+BP=BH+HQ+BP=4+BP+CP=1225.（1)选择方法证明如下因为AD分∠BAC,所以∠BAD=∠CMD,AB=AE.在△BAD和△EAD中，∠BAD=∠EAD,AD=AD.所以△BAD≌△AD(SAS).

"It's an insight into how they build up their picture of space, adds Richard Holland,a biologist at Bangor University who studies bird navigation. There were already indications that dogs-like many ani- mals,and maybe even humans-can sense Earth's magnetic field.In 2013,Hynek Burda,a sensory ecologist at the Czech U- niversity of Life Sciences Prague who has worked on magnetic re ception for 3 decades,and his colleagues showed dogs tend to o- rient themselves north-south while excreting ()Because this behavior is involved in marking and recognizing field,Burda reasoned the line-up helps dogs figure out the location relative e to other spots.But fixed line-up isn't the same thing as navigation.
