Txiav txim siab seb koj chav puas yog lub xwmfab zoo tshaj plaws yuav pab ua kom zoo nkauj, tabsis tseem yuav pab thaum lub sijhawm tsim kho ntawm ib qhov haujlwm uas koj xaiv los ua haujlwm. Luckily, squaring ib chav yog yooj yim heev. Txhua yam koj xav tau yog qee qhov ntsuas kab xev thiab xaum. Yog tias koj tab tom sim ua ib chav rau tso cov nplais, saib Txoj Kev 3 kom pib.
Cov kauj ruam
Txoj Kev 1 ntawm 3: Ntsuas Kab Ntsig
Kauj Ruam 1. Ntsuas kab pheeb ces kaum los ntawm tag nrho plaub fab ntawm chav
Siv daim kab xev ntsuas thiab ntsuas qhov deb ntawm ib ces kaum mus rau nws kab pheeb ces kaum, thiab tom qab ntawd ntsuas kab pheeb ces kaum nruab nrab ntawm ob sab ntxiv. Yog tias koj tau hlua kab hla cov ces kaum koj ntsuas, lawv yuav tsim "X".
Kauj Ruam 2. Paub tias yog qhov ntsuas sib npaug ib leeg, koj chav nyob yog square
Qhov ntawd tsuas yog muaj rau nws! Yog tias koj qhov kev ntsuas tsis sib npaug ib leeg, kho qhov sib dhos kom txog thaum kab pheeb ces kaum sib npaug ib leeg.
Txoj Kev 2 ntawm 3: Siv Pythagorean Theorem
Kauj Ruam 1. Ntsuas 3 ko taw (lossis meters) los ntawm kaum ntawm ib phab ntsa thiab ua cim
Koj tuaj yeem siv txhua chav ntsuas koj xav tau tsuav koj nyob zoo ib yam.
Kauj Ruam 2. Ntsuas 4 taw (1.2 m) ntawm phab ntsa uas nyob ib sab ntawm tib lub ces kaum
Ua tus cim.
Kauj Ruam 3. Nrog rau qib lossis lwm yam khoom ncaj, ncua qhov nrug nruab nrab ntawm ob lub cim
Yog tias txoj kab ncaj nruab nrab ntawm ob lub ntsuas ntsuas 5 taw (1.5 m), lub ces kaum tshwj xeeb yog lub kaum sab xis 90 ° zoo meej.
- Cov txheej txheem zauv uas koj siv los ntsuas lub ces kaum hu ua Pythagorean theorem. Nws hais tias cov xwm txheej ntawm ob sab me me ntawm daim duab peb sab yog sib npaug rau cov xwm txheej ntawm sab ntev: a2 + b2 = c2 Tsuas yog txoj cai peb sab tuaj yeem siv rau hauv Pythagorean theorem, yog li yog daim duab peb sab tus lej tsis ntxiv, ces kaum ntawm daim duab peb sab tsis yog 90 °.
- Koj tsis tas yuav siv 3-4-5 raws li koj qhov kev ntsuas. Koj tseem tuaj yeem ua ob npaug, triple, plaub npaug, thiab lwm yam kev ntsuas yog tias koj chav nyob loj heev. Ntsuas 6-8-10 yog qhov zoo ib yam li ntsuas 3-4-5.
Kauj Ruam 4. Rov ua cov txheej txheem los ntawm peb lwm lub ces kaum
Yog tias lawv txhua tus 90 ° lub kaum ntse ntse, thiab txhua phab ntsa sib npaug, koj tau txais koj tus kheej ib chav square.
Txoj Kev 3 ntawm 3: Squaring Chav Rau Ntoo lossis Pobzeb Flooring
Txoj kev no txawv me ntsis ntawm cov txheej txheem saum toj no. Hloov chaw ntawm kev txiav txim siab seb chav nyob zoo ib yam xwm txheej, txoj hauv kev no qhia koj yuav txiav txim siab li cas nruab nrab ntawm ib chav yog tias nws yog xwmfab. Qhov no yog qhov tseem ceeb heev rau kev tso ntoo hauv tsev lossis pobzeb.
Kauj Ruam 1. Nrhiav cov ntsiab lus nruab nrab ntawm txhua plaub phab ntsa hauv chav
Siv daim kab xev ntsuas, ntsuas tawm txhua phab ntsa, thiab tom qab ntawd faib tag nrho qhov ntev ntawm txhua phab ntsa ib nrab. Ua tus cim ntawm txhua phab ntsa raws nws qhov chaw nruab nrab.
Kauj Ruam 2. Txuas ob qho cim ntawm cov phab ntsa rov qab nrog kab kab kab
Nqa ib daim kab xev thiab muab nws hla nruab nrab ntawm chav kom txuas ob lub hauv paus ntsiab lus hla ntawm ib leeg. Tom qab ntawd mus rau ntawm phab ntsa uas nyob ib sab thiab rub lwm daim kab xev hla chav. Koj yuav tsum muaj lub cim "+" uas sib ntsib hauv nruab nrab ntawm chav.
Kauj Ruam 3. Pib tso koj cov ntoo lossis cov nplais, siv "+" ua koj qhov pib
Yog tias koj tab tom tso ntoo hauv tsev, nco ntsoov tawm ntawm 1⁄2 nti (1.3 cm) tsis nyob ntawm txhua plaub phab ntsa, raws li ntoo xav tau qhov chaw nthuav dav thiab cog lus. Yog tias koj nruab ntoo kom ncaj rau txhua phab ntsa ntawm ib chav, koj yuav muaj peev xwm tawg hauv ntoo thaum nws tsis muaj chav nthuav.
