How kuwana pakakwirira Triangle?

Nokuti matambudziko akawanda geometric vanofanira kuwana kureba rakapihwa chimiro. matambudziko aya vane inoshanda ukoshi. Panguva yaivakwa kukwirira kutsunga kunobatsira ngaaverenge zvakakodzera huwandu zvokunyama uye kuti vaone sei zvakanaka akaita dzakatenuka uye mawindo. Kazhinji kuvaka mapatani vanofanira kungwarira zvivako zviri geometric nenhamba.

Nokuti vanhu vazhinji, pasinei vapase kuchikoro, pakuvaka nyore geometric manhamba kunomutsa mubvunzo sei kuwana kureba netriangle kana parallelogram. Uyezve, tsanangudzo kukwirira Triangle ndiyo kuoma. Izvi imhaka yokuti Triangle zvinogona chakasimba, obtuse, isosceles kana rectangular. Nokuti mumwe nomumwe mhando zvokuridza vane mitemo okuvaka kukarukureta yavo.

How kuwana kukwirira Triangle umo pamakona ose yakapinza, nzira kwakajeka

Kana pamakona ose vane rikwanise netriangle (neimwe pakona rimwe Triangle ndiyo madhigirii asingasviki 90), ipapo kuwana kukwirira kuitwa inotevera.

1. Maererano kuisa parameters yacho Triangle asingavaki.
2. We kuzozivisa notation. A, B uye C ndivo vertices ari nhamba. The pamakona zvakafanana nomumwe vertex - α, β, γ. Pakatarisana runo makona - A, B, C.
3. Urefu anonzi perpendicular akadonha kubva vertex kusvikira pakatarisana kurutivi Triangle. Kuti tiwane Triangle dzakakwirira abate perpendiculars kuvaka: asi vertex yorusvingo α kurutivi mumwe, kuti vertex yorusvingo β kurutivi b, uye zvichingodaro.
4. Pfungwa mharadzano rakakwirira uye kurutivi runotaurwa H1, asi H1 yakakwirira chaizvo. Pfungwa mharadzano kwayo uye divi b ndiye H2, nekukwirira H2, ukuwo. C kurutivi kukwirira ndiye h3, uye H3 kuyambuka pfungwa.

Next, nerimwe mhando netriangle tichashandisa chete notation mativi, pamakona, miti uye vertices ose zvokuridza.

Kukwirira Triangle pamwe obtuse angled

Zvino chitarisa sei kuwana kureba netriangle kana mumwe angled ari obtuse (kupfuura 90 madhigirii). Panyaya iyi, nokukwirira nokubuda kubva obtuse yorusvingo riri mukati Triangle. Vamwe vaviri kukwirira achava kunze Triangle.

Ngatitii pane netriangle ichi pamakona α uye β achava inopinza, uye pakona γ - imwe obtuse. Ipapo kuvaka kuzvikomo, vobuda makona α uye Beta, zvinokosha kuramba zvakapesana dzavo panhivi netriangle, kuti perpendicular.

How kuwana pakakwirira isosceles Triangle

In munhu akadaro pane vaviri vakaenzana mativi uye nechepasi, sezvamakaropafadzwa pamakona vari mujinga, vari zvakare kuenzana mumwe. kuenzana uku kumativi uye pamakona hwezvekukurukurirana chivakwa kukwirira dzavo kukarukureta.

Chokutanga, swedera netriangle pacharo. Regai mativi B c, uye dzinoita β, γ muri azvaitwa vakaenzana.

Zvino kuvhomora kukwirira kubva vertex pamusoro angled α, izvozvo runotaurwa H1. To pakakwirira uyu isosceles Triangle iri panguva imwe bisector uye evaMedhia.

Next, isu kuvaka mamwe maviri kukwirira: H2 kudivi B pakona β, h3 kurutivi C uye pakona γ. dzakakwirira Ava vakaenzana pakureba.

Nokuti nechigadziko, unogona chete kuita chimwe chinhu kuvaka. Somuenzaniso, muMedhia akapiwa anopedza - a chidimbu unobva vertex ane isosceles netriangle uye rumwe rutivi, mumwe muzinda kuwana kukwira uye bisector. Uye kuverenga kureba nokureba mamwe mativi maviri anogona kuvaka imwe chete nokukwirira. Saka, kuti yakanyatsotsanangura kutsanangura sei kuverenga kukwirira isosceles Triangle, dzakakwirira maviri zvakakwana kuwana matatu.

How kuwana kureba netriangle zvakanaka

In netriangle kodzero yokusarudza kureba zvizhinji nyore pane vamwe. Izvi nokuti pachavo makumbo kurudyi pamakona, uye saizvozvo dzokumusoro.

Kuvaka wechitatu pakakwirira, senguva dzose, ari perpendicular kubatana vertex rwerudyi yorusvingo uye negwara. Somugumisiro, kuti kudzidza kuwana kukwirira Triangle, muchiitiko ichi, zvinotora chivakwa imwe chete.
