Ukuba ufuna nayiphi na imfuneko computing ye ubude unxantathu isosceles

Triangle - enye amanani eziphambili geometry. EyamKelekileyo ukunika oonxantathu ngqo (lowo engile ilingana 90 ⁰⁾ kunye obtuse (ixabiso engile ngaphantsi kwe-90 okanye ^0, ngokulandelelana) ostro-, isosceles kunye alinganayo. In izibalo kusetyenziswa iintlobo ngeentlobo nezimaphambili ezingundoqo zejometri kunye neemfundiso ezisisiseko (sine, median radius, nkqo, njalo njalo)

Umxholo uphando lwethu luya kuba ukuphakama unxantathu isosceles. Lokumba isigama kunye neenkcazelo, asiyi nje ngokufutshane ukubonisa nezimaphambili ezingundoqo aza kuzisebenzisa ukuze baqonde uqobo.

Ngoko ke, i unxantathu isosceles kuthathwa ukuba unxantathu apho ixabiso wamacala amabini wavakalisa inani elifanayo omnye (ukulingana ingalo). unxantathu isosceles inokuba etsolo-angled kunye obtuse, kunye ngqo. Kwakhona kuba alinganayo (onke amacala mzobo bayalingana kwexabiso). Ngokufuthi uyakwazi ukuva: zonke oonxantathu alinganayo isosceles, isosceles kodwa hayi zonke - alinganayo.

Ukuphakama nayiphi kanxantathu ithathwa le nkqo lehla ukusuka kwikona kwicala icala mzobo. Kusebenza icandelo media avela imilo angela kwiziko le wacezela phaya.

Ubude omangalisayo unxantathu isosceles?

• Ukuba ukuphakama, uphose ngelinye icala, oko angumndilili bisector, ngoko ke nxantathu lo isosceles ingqalelo, kwaye vice versa: nxantathu lo isosceles ukuba ubude lathotywa ngomnye wabo zombini bisector kunye udibaniso. Le ukuphakama kuthiwa zaseprayimari.
• Ubude base- kwicala (ngokulinganayo) macala unxantathu isosceles, ziyafana yaye zibe amanani amabini efanayo.
• Ukuba uyazi ukuphakama nxantathu isosceles (njengoko, eneneni, nayiphi na), kunye icala leyo eli ubude sele ihliswe, kunokwenzeka ukuba ukwazi ummandla polygon. S = 1/2 * _(c * h c)

Indlela yokusebenzisa ubude unxantathu isosceles kwi izibalo? Izinto zobumnini ngayo basigcina noseko lwalo, yenza Kuluvo ilandelayo ubamba:

• Ubude basic, ukuba zombini angumndilili yahlula isiseko ibe amacandelo amabini alinganayo. Oku kukuvumela ukuba ukwazi inani kwisiseko kwindawo nxantathu akhiwa ukuphakama, njl
• Njengoko ukuphakama nkqo lo nxantathu isosceles ziya kuqwalaselwa iqela (nomlenze) of the entsha nxantathu lasekunene-engile egqithe. Ukwazi ixabiso ngalinye zamaqela, ngokusekelwe theorem kaPythagoras (ubudlelwane ezaziwayo-kakuhle ezingenamandla ze imilenze kunye hypotenuse ophindwe values) ukubala ixabiso lenani yobude.

Yintoni ukuphakama nxantathu? Ngokubanzi, unxantathu isosceles, ekufuneka thina ukuphakama, aliyeki ukuba njalo ubuntu babo. Ngoko ke, ungalahli ngokufaneleka kwabo kuye onke iifomyula ezisetyenziswe kwezi manani, njengoko injalo. Kuyenzeka ukuba ukubala ubude ubude, ububanzi ukwazi ngesandla, ubukhulu zamaqela, kwaye indawo icala, kwakunye nezinye iparameters eziliqela. Ukuphakama kanxantathu ulingana umlinganiselo othile yala maxabiso. Nika wena ifomula akwenzi ngqiqo ukufumana lula. Ukongeza, ukuba ubuncinane lolwazi, unako ukufumana amaxabiso uze kuphela uqhubeke ukubala ukuphakama.
