Ukudlala nomntwana ngamanani amaninzi ejometri, uyamnceda ukuba aphucule ukucinga kwendawo kunye nengcamango. Uqala ukuqonda ukuba yeyiphi i-square, ijikelezi, i-cubic, i-spherical, ne-rectangular kunye kwaye unokuyicinga ngokucacileyo entloko yakhe. Kwaye kubafundi esikolweni kwisifundo seJometri, ootitshala bahlala bebonisa ukuhleka kwamanani amaninzi, okubangela ukuba kubekho ukulungelelaniswa kweengcali ze-geometric kunye ne-axioms. Kwaye, mhlawumbi, igama elinzima kakhulu nelinzima-ukubiza igama lomntwana "yi-parallelepiped". Ukuze ukwazi ukuqonda eli nani kunye nokuqonda iipatheni zalo, sikhuthaza ukuba wena nomntwana wakho wenze iparalpiped iphepha ngezandla zabo.
Ukwenza oku uya kuyidinga:
- iphepha elinyeneyo (kodwa kungekhona ikhadibhodi, ngaphandle koko umntwana uya kwenza loo mathuba ubunzima obuninzi), unokusebenzisa iphepha kwi-albhamu;
- ipensile;
- umlawuli;
- izikiti;
- glue PVA.
Ukuqonda indlela yokwenza iparallelepiped yephepha, kufuneka ukhumbule indlela ekhangeleka ngayo nokuba yintoni. Eli nani linamacala angama-6, ngalinye liyikhonkco. Ngoko ke, ukukhangela kuyakuquka ii-rectangles ezi-6 ezidibeneyo kwindiza efanayo.
1. Kanye naluphi na umthamo we-volumetric, i-parallelepiped ubude, ububanzi nobude. Kuvela kwintengo yabo ukuba ubukhulu becala buya kuxhomekeka. Chaza inani elifunayo kwaye ubhale phantsi.
2. Siqhuba ukudweba umzobo we-parallelepiped kwiphepha. Khumbula ukuba iphepha akufanele libe lincinci, liza kuba lula limanzi kwi-glue kwaye lixilwe, ngoko umfanekiso awuyi kuphuma, kwaye ikhadibhodi ebanzi kakhulu ayiyi kugoba kakuhle kwaye iya kuphahlaza.
3. Dweba umgca ongezantsi, ubude obulinganayo nesixa sobubanzi nobude, buphindwe kabini. Emva koko ukusuka kumgca ngamnye womgca sinciphisa i-perpendicular elinganayo nobude be-parallelogram. Phakathi kwabo udweba umgca ohambelana neyokuqala.
4. Ngoku, ukusuka ekhoneni eliphezulu lasekunene, sicwangcisa ukuphakama kweparallelogram, ngoko ububanzi. Emva koko ubude, kwaye kwakhona ububanzi. Ukusuka kumaphuzu athobileyo, gwala imida engaphaya kwinqanaba, eliya kulingana nobude be-parallelogram. Ngoko sinobuso obomine obunjani. Kukho ezinye ezimbini ezisele.
5. Ngaphezulu kwesixande sesibili ngakwesokudla, songeza ezimbini kwizantsi nangaphezulu. Kule meko, ukusuka kumatshini wesibini ngakwesokudla, esenza kwisinyathelo 4, sondela i-perpendicular upward elinganayo nokuphakama komfanekiso. Phinda okufanayo ukusuka kumatshini wesibini. Sidibanisa ii-perpendiculars ngecandelo elilinganayo nobubanzi be-parallelogram. Ngendlela efanayo, sakha umxube wezantsi ngaphesheya.
6. Ukuze wenze kube lula ukumbamba i-parallelepiped ephepheni, engeza "amaphiko" eyongezelelweyo kumzobo, njengoko kuboniswe kumfanekiso. Ubanzi bawo bube malunga no-1.5 cm. Kufuneka kwakhona ukuba benze iibhondi (45 degrees), ukwenzela ukuba xa baxhamle bengabhekanga ngaphandle.
Ngoko ke, ukukhishwa kwephepha eliphambene nephepha likulungele. Kubalulekile ukuba zonke iinkcukacha zomdwebo zisezantsi kwaye zilinganiswe ngokungqongqo, ngaphandle koko isibalo asihlangani ngokufanayo kwaye siya kuba yindonga.
7. Sika umsetyenzana uze uyibophe kuyo yonke imizila ukuze amacandelo ethu athinte, kwaye iirectangles eziphezulu nezantsi ziba "ngaphantsi" kwaye "zifihla" kulo mfanekiso.
8. Gubungela "amaphiko" eyongezelelweyo ngeglue kwaye uqokelele i-parallelepiped ngokuzigcwalisa ngaphakathi. Makhe silinde ukuba i-glue idle.
Ukuba uye wazi kakuhle ukuveliswa kwalolu nani, unokuqhubeka ukuqokelela i-parallelepiped ye-parallelepiped yecala, elineedeni ezinobumba obukhulu.
- Ngokufana nomfanekiso wokuqala, bhala umzobo, njengoko kuboniswe kumfanekiso. Njengoko uyakubona, bonke ubuso be-parallelepiped incline bafana kwaye onke amacala edayimane alinganayo.
- Yongeza emfanekisweni onamaphiko anongeziweyo.
- Ngenisa ngobumnene isibalo.
I-Parallelepiped - isalathisi esilula ngejometri, ukuqonda ukuba ungaya kwabanye - ukudala ipiramidi yekhadibhodi okanye iphepha, umzekelo, i- icosahedron .
