Molunjika, yosamveka, lakuthwa, molunjika ngodya

Tiyeni tiyambe ndi tanthauzo la zimene ngodya. Choyamba, ndi chithunzi zojambula. Kachiwiri, aumbike mwa matabwa awiri, amene ayitanidwa mbali njingayo. Chachitatu, otsiriza mwa mfundo limodzi, ndilo lotchedwa vertex kupendekeka kwa. Kuchokera pa makhalidwe amenewa, tikhoza kupanga mtima: ngodya - mawonekedwe zojambula, chomwe ndi matabwa awiri (mbali), wochokera ina (pamwamba).

Iwo ali m'magulu malinga ndi phindu digiri, dongosolo ndi ulemu wina ndi mnzake ndi wachibale circumference a. Tiyeni tiyambe ndi mitundu ya kumathandiza kupeza ngodya zabwino malinga ndi kukula.

Pali mitundu ingapo. Tiyeni tione mtundu uliwonse.

Mitundu ya m'makona onse anayi - molunjika, yosamveka, lakuthwa, molunjika njingayo.

molunjika

Izo zikuwoneka ngati izi:

madigirii ake nthawi zonse muyeso wa ^90, mwa kulankhula kwina, mbali bwino - ngodya madigiri 90. Kamodzi ali quadrangles izi tinamdandaulira lalikulu ndi rectangle.

wosasamala

Iwo ali mawonekedwe:

Digiri muyeso wa mbali obtuse nthawi zonse kuposa ⁹⁰ koma zosakwana ^180. Iwo angayambe quadrangles monga rhombus, ndi parallelogram lachabechabe, mu polygons.

lakuthwa

Izo zikuwoneka ngati izi:

Digiri muyeso wa makona pachimake nthawi zonse zosakwana ⁹⁰ °. Umapezeka onse quadrangles, koma kwa mbali zonse zinayi ndi parallelogram umasinthasintha.

kufalitsidwa

Ena ngodya ndi motere:

The polygons zimachokeradi, koma n'kofunika kwambiri kuposa ena. Molunjika ngodya - mawonekedwe zojambula, digiri muyeso nthawi zonse wofanana 180º. N'zotheka kumanga ngodya pafupi, kuthera ku matabwa ake pamwamba chimodzi kapena zingapo mbali zonse.

Pali zingapo zazing'ono kumathandiza kupeza ngodya zabwino mitundu. Iwo kusukulu, koma mukudziwa osachepera moyo wawo koyenera. Minor ngodya mitundu isanu yokha:

1. Zero

Izo zikuwoneka ngati izi:

Dzina la ngodya kale akulankhula za kukula kwake. Mkati ake 0 ^O, dzanja bodza pa wina ndi mnzake monga tikuonera maonekedwe.

2. oblique

Skew ukhoza kukhala mwachindunji ndi yosamveka ndi lakuthwa, molunjika njingayo. chikhalidwe Aika - sitiyenera kukhala wolingana ⁰ °, ^{90 °, 180} °, 270 ^°.

3. otukukira kunja

Kodi ziro otukukira kunja, molunjika, yosamveka, ngodya lakuthwa ndi kufalitsidwa. Monga inu mukudziwa, muyeso wa digirii otukukira kunja ngodya - kuchokera ⁰ mpaka ^180.

4. nonconvex

ngodya Non-otukukira kunja ndi muyeso wa mlingo wa ^pafupifupi 181 ^pafupifupi 359, kuphatikiza.

5. Full

Ndi ngodya zonse ^za 360 digiri muyeso.

Izi zonse mitundu ya kumathandiza kupeza ngodya zabwino malinga ndi kukula. Tsopano, ganizirani malingaliro awo pa malo a ndege wachibale wina ndi mzake.

1. zoonjezerapo

Awa awiri pachimake njingayo, kupanga mzere woongoka, ie, ndalama zawo ndi ^90.

2. Related

kumathandiza kupeza ngodya zabwino Kubwalo anapangidwa mwa tsatanetsatane, yeniyeni, kudzera vertex ake, gwirani mtengo kwina kulikonse. ndalama zawo ndi wofanana ^180.

3. Mulitali

Ngodya ofukula anapanga ndi mphambano ya mizere iwiri. miyeso awo ndi digiri ofanana.

Ife tifike ku mitundu ya kumathandiza kupeza ngodya zabwino oyenerera wachibale bwalo. Pali awiri okha: chapakati ndi alembedwa.

1. chapakati

Ndi mbali chapakati ndi vertex pa malo a bwalo. madigirii ake ndi muyeso wa digirii osachepera Arc, maphwando aakulu.

2. alembedwa

Lolembedwa ndi ngodya amene vertex lagona pa bwalo, ndi m'mbali umene anawoloka. digiri muyeso wake ndi wofanana Arc theka lomwe amadalira.

Ndi nazo kumathandiza kupeza ngodya zabwino. Tsopano inu mukudziwa kuti kuwonjezera wotchuka kwambiri - lakuthwa, yosamveka, mwachindunji ndi kufalitsidwa - mu masamu, pali ena ambiri a mtundu wawo.
