Chimiro chejometri chinogona kukamurwa zvichienderana nehunhu hwakasiyana.

Munguva yehudiki hwedu, isu tese taifanirwa kuenda kukirasi yemasvomhu kuchikoro, kwataifanira kudzidza mhando dzakasiyana dzeatatu. Nekudaro, nekufamba kwemakore, tinogona kukanganwa zvimwe zvinhu zvatakadzidza. Kune vamwe vanhu mathematics inyika inonakidza, asi vamwe vanofarira nyika yetsamba zvakanyanya.

Muchikamu chino tichaongorora mhando dzakasiyana dzematatu, saka zvinogona kubatsira kuzorodza dzimwe pfungwa dzakadzidzwa munguva yakapfuura kana kudzidza zvinhu zvitsva zvaisazivikanwa.

Kubatsira kwetatu

Mune masvomhu, geometry inodzidziswa, uye inoongorora mumhando dzakasiyana dzejometri dzakadai sematatu. Ruzivo urwu runobatsira pazvikonzero zvakawanda; semuenzaniso: kugadzira michina yekudhirowa kana kuronga nzvimbo yekuvakira nekuvakwa kwayo.

Mupfungwa iyi, uye zvakasiyana nekatekete kanogona kushandurwa kuita parallelogram kana simba rikaiswa kune rimwe remativi aro, mativi etriangle akatsiga. Nekuda kwekuomarara kwemaumbirwo ayo, vafizikiki vakaratidza kuti iyo katatu inogona kumira nesimba rakawanda isina kuora. Naizvozvo, vavaki uye mainjiniya vanoshandisa mativi matatu kana vachivaka mabhiriji, matenga edzimba, nezvimwe zvivakwa. Kana zvitatu zvikavakwa muzvivakwa, kuramba kunowedzera nekuderedza kufamba kwekufamba.

Chii chinonzi Triangle

Iyo Triangle ipolonigoni, yakati sandara geometric nhamba ine nzvimbo asi isina vhoriyamu. mativi matatu ane mativi matatu, matatu uye matatu emakona emakona, uye huwandu hwayo i180º

Triangle inoumbwa ne:

Mune aya manhamba, rimwe remativi emufananidzo uyu rinogara riri pasi pehuwandu hwemamwe mativi maviri, uye mutriangle ine mativi akaenzana, makona ayo akatarisana akaenzanawo.

Maitiro ekuwana iyo nharaunda uye nzvimbo yetriangle

Zviyero zviviri zvatiri kufarira kuziva nezve mativi matatu ndiyo nharaunda nenzvimbo. Kuti uverenge yekutanga, zvinodikanwa kuti uwedzere hurefu hwamativi ayo ese:

P = a + b + c

Pane kudaro, kuti uone kuti nzvimbo yemunhu uyu ndeipi, fomu inotevera inoshandiswa:

A = ½ (bh)

Naizvozvo, iyo nharaunda yeatriangle iri base (b) times kukwirira (h) yakakamurwa nepaviri, uye kukosha kunoguma kweiyi equation kunoratidzwa mune mativi mayuniti.

Ma triangles akarongwa sei

Kune mhando dzakasiyana dzeatatu, uye ivo akarongwa achifunga nezvehurefu hwamativi avo uye hupamhi hwemakona avo. Tichifunga mativi ayo, pane matatu marudzi: akaenzana, isosceles uye scalene. Zvichienderana nemakona avo, tinogona kusiyanisa kurudyi, kufumura, kuomarara, uye equiangular matatatu.

Isu tinoenderera mberi nekudzinyora pazasi.

Triangles zvinoenderana nekureba kwemativi avo

Tichifunga nezvehurefu hwemativi, iwo mativi matatu anogona kuve emhando dzakasiyana.

1. Yakaenzana netriangle

Triangle yakaenzana ine mativi matatu ehurefu hwakaenzana, ichiiita polygon yenguva dzose. Iwo ma engles mune yakaenzana netriangle akaenzana (60º imwe neimwe). Iyo nharaunda yerudzi urwu rwetatu ndiyo mudzi we3 neka4 zvakapetwa urefu hwedivi rakapetwa. Iyo perimeter ndicho chigadzirwa chehurefu hwerimwe divi (l) uye matatu (P = 3 l)

2. Scalene triangle

Triangle yekalene ine mativi matatu ehurefu hwakasiyana, uye makona ayo anewo zviyero zvakasiyana. Iyo perimeter yakaenzana neuwandu hwehurefu hwamativi ayo matatu. Izvi zvinoreva: P = a + b + c.

3. Isosceles katatu

Isosceles triangle ine mativi maviri akaenzana uye mairi mairi, uye nzira yekuwana mukombero wayo ndeiyi: P = 2 l + b.

Triangles maererano nemakona avo

Triangles inogona zvakare kusarudzwa zvinoenderana nehupamhi hwemakona avo.

4. Triangle kurudyi

Ivo vanozivikanwa nekuve nekona yemukati kona, ine kukosha kwe90º. Makumbo ndiwo mativi anoumba kona iyi, nepo fungidziro ichienderana nedivi rinotarisana. Nzvimbo yekatatu iyi chibereko chemakumbo ayo akapatsanurwa nepaviri. Ndokunge: A = ½ (bc).

5. katatu

Rudzi urwu rwehutatu rine kona yakakura kupfuura 90 ° asi iri pasi pe180 °, iyo inonzi "obtuse", uye maakona maviri akaomarara, ari pasi pe 90 °.

6.Acute triangle

Rudzi rwemakona matatu runoratidzwa nemakona aro matatu ari pasi pe90 °

7. Makona matatu akaenzana

Iyo yakaenzana netriangle, nekuti makona ayo emukati akaenzana ne60 °.

mhedziso

Chaizvoizvo isu tese takadzidza geometry muchikoro, uye isu tinoziva mativi matatu. Asi pamusoro pemakore, vanhu vazhinji vanogona kukanganwa hunhu hwavo uye kuti vanoiswa sei. Sezvawaona muchinyorwa chino, mativi matatu akarongedzwa nenzira dzakasiyana zvichienderana nehurefu hwamativi awo uye hupamhi hwemakona avo.

Geometry chidzidzo chinodzidziswa mumathematics, asi havazi vese vana vanofarira chidzidzo ichi. Kutaura zvazviri, vamwe vane matambudziko akakomba. Ndezvipi zvikonzero zveizvi? Muchinyorwa chedu "Zvinetso zvevana mukudzidza masvomhu" tinozvitsanangurira.
