Yuav ua li cas kom kawm tau qhov Geometry thiab protractor luam tawm?

Geometry, zoo li txhua yam txuj tshawb fawb, tsis ua rau tus cwj pwm tsis zoo. Thiab los pab nws kawm txog kev qhia, cov me nyuam yuav tsum ua qhov me me rau txoj kev koob tshuaj. Nws lub ntsiab ntsiab lus yuav tsum: yuav ua li cas thiaj ua rau cov tshuaj tiv thaiv. Yuav ua li no, koj xav tau me ntsis: txiab, kua nplaum, A4 daim ntawv, tuab duab ntawv, cwj mem, cov cim, xim, txhuam, ntau yam kev dai kom zoo nkauj, luam ntawv, zoo, qhov twg tsis muaj tuj siab ntev thiab lub hnab ntawm kev tshoov siab! Qhov yuav tsum tau ua haujlwm zoo li no ua ntej tus menyuam tuaj yeem sib cav los ntawm qhov tsis tuaj yeem pom qhov chaw tseem ceeb hauv lub khw lossis hauv cov tswv yim zoo dua.

Npaj cov haujlwm

Thawj qhov uas yuav poob rau ntawm koj lub xub pwg nyom yog kev npaj ntawm ib lub qauv. Nyob rau ntawm tam sim no, nws tsis yog yooj yim mus nrhiav tau ib tug haum variant. Yog tias koj muaj cov graphic editors, koj tuaj yeem tsim ib tus qauv nrog koj tsev neeg cov duab, npe, cov cim koj nyiam cartoons. Tab sis tsis txhob mus nqa deb, tom qab tag nrho, koj tau txais ib daim ntawv dawb xim tawm - luam tawm, thiab sib koom tes nrog lub ntsiab ntawm kev kawm yuav npau taws.

Ib qho kev daws teeb meem zoo tshaj yuav yog los npaj cov contour nrog cov txheej txheem digital uas yuav tau pleev xim thiab ua kom zoo dua txhua txoj kev. Kuj nws yog tsim nyog yuav tau txiav txim siab seb hom tshuaj tiv thaiv rau sau - kab kev simplicity ntawm zaub, semicircle nrog qhov tseem ceeb ntawm 0 mus rau 180 degrees. Yog tias txoj kev yooj yim tsis yog rau koj, peb niaj hnub tig mus rau cov hau kev los sawv cev ntawm cov kev paub txog trigonometry.

Ib qho kev mus ncig ua si rau hauv keeb kwm thiab me ntsis txog tam sim no

Ua ntej lub txiav txim zaum kawg hais txog dab tsi zoo ntawm ib tug protractor luam, koj yuav tau qhia rau koj tus me nyuam ntawm cov keeb kwm ntawm qhov ntsuas (nws tuaj ntawm ancient Babylon), yuav ua kom paub cov sexagesimal system ntawm xam thiab nws cov tswv yim - degrees, feeb, vib nas this. Nws yuav tsis yooj yim rau kev sib txuas ntawm kev siv cov ces kaum hauv lub neej niaj hnub no, hauv geodesy thiab cartography, hauv kev tsim kho, hauv tshuab lub tsev, thiab lwm yam., Los qhia cov ntsiab lus ntawm cov ces kaum - khoob khoob khoob khoob khoob khoob khov, nthuav, nthuav tawm, thiab piav qhov txawv ntawm lawv. Nws raug pom zoo kom peb qhia peb tus kheej los tso saib cov ces kaum ntawm peb tus kheej kom lawv siv tau los tsim cov duab kos rau qee yam. Thaum lub sijhawm no ua tiav, xyuas seb qhov pov npav puas tawm tau li cas: nws yog ib qhov tsim nyog los xyuas qhov zoo ntawm daim qauv npaj ua ntej thiab hauv qhov kev daws teeb meem. Lub tshuab luam ntawv yuav tsum tso tawm cov ntaub ntawv tsis muaj teeb meem los yog distortion. Koj yuav tsum tau tu nws los yog kho nws.

Cov txheej txheem muaj tswv yim

Tom qab txiav txim siab seb hom tshuaj tiv thaiv twg tawm, koj tsuas nias rau ntawm "Sau" button (koj tuaj yeem hais ntau yam ntawv luam), thiab txiav tawm rau sab nrauv raws tus contour. Nws yog tsim nyog yuav tsum tau ceev faj, vim hais tias tej yam tsis muaj leej twg yuav pom hauv. Thiab ces mus rau decorating lub protractor. Ua li no, txhua yam tsim nyog, qhov kev xaiv nyob ntawm seb ntau npaum li cas koj mob siab txog kev lag luam.

Txhua hom kev sib txuas ntawm cov xim, paj rwb thiab cov ribbons ntawm ntau cov duab ntxoov ntxoo, ntaub plaub, paj rwb ntaub, stickers, hlaws, cov nquab thiab cov hneev yuav nrhiav kev siv, vim qhov no lawv yuav tsis yog qhov tsis zoo. Tom qab qhov kawg ntawm tus txheej txheem, qhov nuj nqis artistic ntawm tus protractor yuav ua rau ntau ntau-fold, nws tuaj yeem muab los rau hauv cov duab los qhia thiab ua ib lub qhov cim ntawm qhov ntsuas pib. Dua li ntawm qhov tseeb hais tias qhov kev ua tus kheej no yuav tsis yooj yim dua siv nws cov neeg ua haujlwm uas tsis yog lub koom haum, nws yuav tsis cia leej twg tsis nyiam vim nws txoj kev ntxim hlub thiab tus qauv tsim. Tej yam kev ua si nrog tus me nyuam yuav muab sij hawm ntau rau koj rau yav tom ntej.
