Thawj lub kaum sab xis projection yog ib txoj kev tsim a2D daim duab ntawm ib qho khoom 3D. Nws yog siv nyob rau hauv cov teb chaws Europe thiab Asia thiab tsis tau officially siv nyob rau hauv Australia tau ntau xyoo. In Australia, thib peb lub kaum sab xis projection yog txoj kev nyiam orthographic projection . Nco ntsoov lub cim rau thawj lub orthographic projection.
Ua raws li qhov no hauv kev xav, qhov txawv ntawm thawj lub kaum sab xis thiab qhov thib peb lub kaum sab xis orthographic projection yog dab tsi?
Kom tau txais cov thawj lub kaum sab xis projection , qhov khoom tso hauv thawj quadrant lub ntsiab lus nws tau muab tso rau nruab nrab lub dav hlau ntawm qhov projection thiab tus neeg soj ntsuam. Forthe peb lub kaum sab xis projection , cov khoom yog muab tso rau hauv qab thiab qab ntawm lub dav hlau saib lub ntsiab lus ntawm lub dav hlau qhov projection yog nruab nrab tus soj ntsuam thiab cov khoom.
Ib sab saum toj, dab tsi yog 3 lub ntsiab lus ntawm kev kos duab orthographic? Feem ntau, ib orthographic projection kos duab muaj peb qhov sib txawv :a pem saib , atop saib , thiab ib sab saib . Qee zaum, ntau dua saib yog siv rau clarity. Sab saib feem ntau yog sab xis, tab sis yog tias sab laug siv, nws tau sau tseg rau hauv daim duab.
Nyob rau hauv no txoj kev, dab tsi yog qhov kev siv ntawm thawj lub kaum sab xis projection?
First Angle Projection feem ntau yog siv hauv txhua lub tebchaws uas tsis yog Tebchaws Meskas. Indian StandardInstitution (ISI) pom zoo rau siv First AngleProjection txoj kev tam sim no nyob rau hauv tag nrho cov koom haum. Peb AngleProjection feem ntau yog siv hauv Tebchaws Meskas.
Vim li cas peb thiaj siv 1st thiab 3rd lub kaum sab xis projection?
Ua ntej ntawm txhua yam, peb siv thawj lub kaum sab xis thiab peb lub kaum sab xis projection vim tias nws tau xav tias lub dav hlau kab rov tav yog tig CLOCKWISE coj lawv mus rau tib lub dav hlau (rau lub hom phiaj kos duab) thiab yog tias peb siv thib ob lossis plaub. angle projection , ces Kab rov tav thiab ntsug views yuav overlap, tsim kev tsis meej pem hauv lawv

Dab tsi yog lub kaum sab xis ntsuas hauv daim duab peb sab ABC?
Kev piav qhia ib kauj ruam dhau los: Nws tau muab tias ABC yog lub kaum sab xis uas yog kaum sab xis ntawm C thiab AC = 7 ntiv tes thiab CB = 5 ntiv tes. Yog li, qhov ntsuas ntawm cov kaum sab xis uas ploj lawm hauv daim duab peb sab ABC yog 35.5 ° thiab 54.5 ° feem
Cov kab lus hloov sab hauv cov ces kaum piav qhia txoj haujlwm ntawm ob lub kaum sab xis li cas?
Hloov sab hauv cov ces kaum yog tsim los ntawm ib tug transversal intersecting ob parallel kab. Lawv nyob nruab nrab ntawm ob qho tib si kab tab sis nyob rau sab nraud ntawm lub transversal, tsim ob khub (plaub tag nrho cov ces kaum) ntawm cov ces kaum sab hauv. Hloov cov ces kaum sab hauv yog congruent, txhais tau tias lawv muaj qhov sib npaug
Koj tuaj yeem ua pov thawj li cas 2 daim duab peb sab zoo sib xws siv lub kaum sab xis sab SAS zoo sib xws postulate?
SAS Similarity Theorem hais tias yog ob sab hauv ib daim duab peb sab yog proportional rau ob sab hauv lwm daim duab peb sab thiab lub kaum sab xis nyob rau hauv ob qho tib si congruent, ces ob daim duab peb sab zoo ib yam. Ib qho kev hloov pauv zoo sib xws yog ib lossis ntau qhov kev hloov pauv tsis tu ncua ua raws li kev dilation
Dab tsi yog txoj cai kaum rau lwm lub kaum sab xis?
Hloov cov ces kaum sab hauv yog tsim thaum lub transversal hla dhau ob kab. Lub kaum sab xis uas tsim nyob rau sab nraud ntawm lub transversal thiab sab hauv ob kab yog alternate sab hauv cov ces kaum. Lub theorem hais tias thaum cov kab sib npaug, qhov sib txawv sab hauv cov ces kaum sib npaug
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
