Distanta dintre doua puncte, dintre un punct si o dreapta, si un plan, dintre doua drepte paralele, Aplicatii Probleme, Exemple ...e Pentru calcularea distantei de la un punct la o dreapta construim perpendiculara din acel punct pe acea drepta si cautam un triunghi eventual dreptunghic in care aceasta distanta sa fie o latura sau linie importanta.Observatie2 Segmentul cel mai scurt de la un punct exterior unui plan la acel plan este segmentul perpendicular pe planul dat.Aplicatii1Ip.ABC isoscelABAC15cm, BC18cmAMABC, AM12 EMBED Equation.3 dist.M, BCDem.Ducem ADBC, DBCAMABCADBCT.3..ADABC MDBC dist.M,BCMDBCABCABC isoscel AD mediana BDDC BDDC9AD inaltime dar BC18ADBC ABD dreptunghic AD2AB2-BD2 AD2225-81 AD2144 AD12AMABC AMAD MAD dreptunghicADABC MD2MA2AD2MD21443144MD21444MD242Ip.ABC dreptunghic mA90AMABC, AM3cm EMBED Equation.3 AB6cm, AC6 EMBED Equation.3 dist.M, BCDem.Ducem ADBC, DBCAMABCADBCT.3..ADABC MDBC dist.M,BCMDBCABCAMABC AMAD MAD dreptunghicADABCABC dreptunghic BC2AB2AC2 BC236108 BC2144 BC12ADBC AD inaltime AD EMBED Equation.3 AD EMBED Equation.3 ABC dreptunghic AD EMBED Equation.3 MAD dreptunghic MD2AM2AD2 MD2927 MD225 MD53Ip.ABCD dreptunghi, AB16cm, Bc9cmAMABC, AM12cmdist.M, ABdist.M, BCdist.M, CDdist.M, ADDem.AMABC MAAD dist.M, ADAM12ADABCAMABC MAAB dist.M, ABAM12ABABCAMABC T.3..ADDC MDDC dist.M, DCMDADABCDCABCAMABC T.3..ABBC MBBC dist.M, BCMBABABCBCABCMAAD MAD dreptunghic MD2AM2AD2MD214481MD2225MD15MAAB MAB dreptunghic MB2AM2AB2MB2144256MB2400MB204Ip.ABCD dreptunghiACBDIOS, AB32cm, BC18cmOMABC, OM12cmC.dist.M, ABdist.M, BCdist.M, CDdist.M, ADDem.Ducem OEAB, EABOFBC, FBCOGDC, GDCOHAD, HADOMABC T.3.OEAB MEAB dist.M, ABMEOEABCABABCOMABC T.3.OFBC MFBC dist.M, BCMFOFABCBCABCOMABC T.3.OGCD MGAB dist.M, CDMGOGABCCDABCOMABC T.3.OHAD MHAD dist.M, ADMHOHABCADABCABCD dreptunghi AOaOCBOaOD AOB, BOC, COD, AOD isosceleACaBDAOB isoscel OE mediana AEaEB AEEB16OE inaltime AB32BOC isoscel OF mediana BFaFC BFFC9OF inaltime BC18COD isoscel OG mediana CGaGD CGGD16OG inaltime CD32AOD isoscel OH mediana DHaHA AHHA9OH inaltime AD18OEAB ADQEOADAB AEON paralelogram OE9OEAE AEQONOEONOFBC ABQOFABBC EBFO paralelogram OF16OEAB OEQBFFBABOGDC OGQFCFCDC OFCG paralelogram OG9OFBC GCQOGGCBCONAD ONQGDCDAD NOGD paralelogram OE16NDDC NDQOGOGDGMOE dreptunghic ME2OM2OE2ME214481ME2225 ME15MOF dreptunghic MF2OM2OF2MF2144256MF2400 MF20MOG dreptunghic MG2OM2OG2MG214481MG2225 MG15MOH dreptunghic MH2OM2OH2MH2144256MH2400 MG20PAGE PAGE 6DMCBAABCMDABCDM16912636 EMBED Equation.3 151512 EMBED Equation.3 ABCDOMEFGH321812O8rd8prvxŕartvzi02468Ztbdfhjlnp...
