Nokuti chero kadambari chikonzero ane isosceles Triangle kukwirira

Triangle - mumwe zvikuru mukufambisira geometry. Yakabvuma zvinopa yakananga zvokuridza (ane angled akaenzana 90 ⁰⁾ uye ostro- obtuse (angled kukosha asingasviki 90 kana ^{0 ukuwo),} isosceles uye equilateral. Munguva Masvomhu vaishandisa nekuve dzinokosha geometric pfungwa uye anokoshesa (sine, evaMedhia nharaunda, perpendicular, etc.)

Musoro yokutsvakurudza yedu ichava pakakwirira isosceles Triangle. Yakawanda yokunyatsoongorora mazwi uye tsanangudzo, isu hatingazvirumbidzi chete zvishoma kureva dzinokosha pfungwa hunozodiwa kunzwisisa unhu.

Saka, imwe netriangle isosceles iri kuonekwa netriangle umo kukosha rwemberi akaratidza imwe nhamba rimwe (wakaenzana maoko). Isosceles netriangle inogona chakasimba-angled uye obtuse, uye yakananga. Zvingavawo equilateral (kumativi ose Nhamba dziri rwaikosha). Kazhinji unogona kunzwa: zvose equilateral zvokuridza isosceles, isosceles asi kwete vose - equilateral.

Kukwirira upi netriangle ichaongororwa ari perpendicular akadonha kubva pakona uri divi nhamba. It anoita somunhu vezvenhau chidimbu wakavhomorwa kubva chimiro rekona iri nechepakati nokune rumwe rutivi.

The chinoshamisa Kukwirira ane isosceles Triangle?

• Kana kumusoro, akadonha rumwe rutivi, ndizvo muMedhia akapiwa uye bisector, ipapo Triangle iri isosceles vaiona, ndiEzekieri: asi Triangle iri isosceles kana kureba kudzikiswa rimwe mapato zvose bisector uye evaMedhia. kukwirira iyi inonzi chepuraimari.
• Urefu kutura kurutivi (yakaenzana) mativi ane isosceles Triangle, akafanana uye kuumba mifananidzo miviri yakafanana.
• Kana uchiziva kukwirira isosceles Triangle (sezvo, zvirokwazvo, zvimwe), uye kurutivi iro pakakwirira ichi rave chichiburutswa, zvinokwanisika kuziva nzvimbo yacho polygon. S = 1/2 * _(c * bare c)

How kushandisa kureba ane isosceles netriangle ari Masvomhu? Properties nayo vaitevedzera chawo, kuti zvinotevera kutaura rinei:

• The inokosha urefu, ari zvose evaMedhia rinokamukana mujinga huviri zvakaenzana zvikamu. Izvi anotibvumira kuziva uwandu zvitsigiro nzvimbo Triangle inoumbwa kumusoro, etc.
• Sezvo perpendicular kukwirira isosceles Triangle kunganzi bato (gumbo) itsva Triangle zvakanaka-angled. Kuziva kukosha nerimwe kumapati, inobva Pythagorean theorem no (rinozivikanwa yomumba makumbo uye hypotenuse akaenzana tsika) kuverenga nhamba kukosha kumusoro.

Chii kukwirira Triangle? Kazhinji, imwe isosceles Triangle, izvo tinoda urefu, harimiri kudaro avo chaizvo. Saka, regai rirasikirwe kwavo kwaari vose Masvomhu inoshandiswa nhamba idzi, sezvo vakadaro. Zvinokwanisika ngaaverenge kukwirira urefu, pamakona uye achiziva ruoko, kwakakura mapato, uye kurutivi nzvimbo, uyewo mamwe parameters akawanda. Kukwirira Triangle akaenzana mumwe nhamba tsika idzi. Zvipe kuti nzira hazvina musoro kuti kuzviwana nyore. Uyezve, kuva zvishoma mashoko, unogona kuwana tsika uye chete ipapo mberi kuverenga urefu.
