E like me ka 'epekema i haʻawina' ana i ia i ka triangle a me nā mea i kona waiwai i trigonometry. Ua huli i au mamuli a pau o kaʻike manaʻo pili i kēia mau geometric kinona. Ka mea i like me ka triangle, mākou e'ōlelo i kēia lā i loko o kā mākou 'atikala. Ka eia e kakau i ko lakou mau ano, e like me ka pono me kekahi theorems e pili ana me ia.

He aha mea he triangle? ka wehewehena

He He palahalaha iieeaii. Ua he mau kihi ekolu, ia mea hala ole oe i kona inoa. Nō hoʻi ka mea, he ekoluʻaoʻao a me vertices ekolu, i ka mua o ia - e hiki, o ka lua - o ka wahi. Ua ike hoi oia i mau pana pua e like, hiki ke loaʻa ma ka unuhi i ka huina o ka mua elua o ka helu 180 ke kolu.

He aha nā triangle mauna?

Ka mea hiki ke hoʻolaha e like me ka mau ana hoʻohālike.

Mua o nā mea a pau, ka mea, ua māheleʻia aʻela ma luna o pahi-ka makau, a me ka obtuse huinahń loa. Ka mua i mau pahi pana pua, i mea, ka poe i emi mai o 90 degere. I kekahi o ka obtuse kihi - obtuse, a laila kekahi i mea oi ma mua o 90 degere, ka mea'ē aʻeʻelua - huʻi. No ka huʻi triangle mea i equilateral. Oia triangle mauna a pauʻaoʻao a me ka pana pua i like. e like me 60 degere a pau o ia mau mea, e hiki e pōpilikia maʻalahi ma ka mahele ana i ka huina o nā pana pua (180) ma ekolu.

pono triangle

He mea hiki ole i ke kamailio e pili ana i ka mea pono-huina triangle.

Ma ia he huahelu o ka huina o 90 degere (pololei), a laila, loaʻa nō nā o kona aoao hoonohonoho perpendicularly. Ka i koe, kihiʻelua, Ua lena. Ka mea, i e like, alaila ia mea he isosceles triangle. Me ka huina triangle e pili ana i ka Pythagorean theorem. Me ke kōkua o ka mea e hiki ke loaʻa i ke kolu o ka aoao, e ike ana i ka mea mua elua. E like me ia i kēia theorem, ina ua hui i ka hale o kekahi wāwae a hiki i ka 'ē aʻe huinahalike, e hiki ke kiʻi i ka huinahalike o ka hypotenuse. Ke huinahalike wāwae hiki ke ho omaulia ma ka unuhi i ka hale o ka hypotenuse o ke kahua o ka'ūhā kaulana. Kaawale mai ka mea ia ia ka triangle, oe ke hoomanao e pili ana i na isosceles. He mea i loko i nā o na aoao elua e i kau like, a me nā kihiʻelua.

He aha mea he uha mua a me ka hypotenuse?

Cathetus - o kekahi o ka triangle aoao, a hana i ka huina o ka 90 degere. Hypotenuse - kaʻaoʻao ka i koe i ka mea ku pono ana i ka huina akau. Mai kona mau wāwae, e hiki mai hapai ku i ka p ÷ haku. Ka lākiō o ka mea e pili wāwae a hiki i ka hypotenuse Ua haawiia keia i like cosine, a me ke ku pono - sine.

Aigupita triangle - He aha nō kona 'ano?

He Aloha pono. Kona'ūhā, ua like me ekolu a me ka eha, a me ka hypotenuse - elima. Inā eʻike i nā wāwae o ka triangle e like i ekolu eha paha, e hiki eʻoiaʻiʻo i ka hypotenuse mea like i ka elima. Nō hoʻi, e like me keia rula hiki ke eaaei hoʻoholo i ka uha mua, e ia ekolu ina o ka lua o ka mea like i ka eha, a me ka hypotenuse - elima. E hoao i kēia'ōlelo, ua hiki ke hoʻohana i ka Pythagorean theorem. Inā mau cathetus, he 3 a me ka 4, alaila, 9 + 16 = 25, ke kumu 25 - He 5, lākou, a laila hypotenuse 5. A o kanaka o Aigupita i kapaia o huinahń triangle kona aoao e like me 6, 8 a me 10; 9, 12 a me 15, a me nā helu a me ka lākiō 3: 4: 5.

Pehea'ē aʻe hiki ia i ka triangle?

No hoi triangle mauna hiki ke kākau a me ka hoakakaia. Ke Kii a puni e hōʻike ana i ke kaiapili kākauʻia i kapaia, a pau o kona vertices i na mea nui e moe ana ma luna o ka hoa kanaka. Ka triangle - kekahi ma i ka kākauʻia p ÷ ai. Konaʻaoʻao e hele mai i loko o hui 'ana me ia ma kekahi mau wahi.

Pehea o ka wahi o ka triangle?

O ka 'āpana o kekahi huahelu ua anaia ma huinahalike huahelu (sq. Mika sq. MM, sq. Kenimika sq. Decimetres, a no laila,. D.) kēia waiwai hiki ke ho omaulia ma kela aoao, kaukaʻi wale ma luna o ka' ano o triangle. Area mea shape a me kona mau kihi Hiki ke loaʻa ma ka hoonui konaʻaoʻao i loko o ka p ÷ haku ma luna o ka mea, mai ke ku pono ana huina, a me ana i kēia huahelu e mau. E hiki no hoi loaʻa i kēia nui e hoonui i kaʻaoʻaoʻelua. A laila, e hoonui i ka helu ma ka sine o ka huina aia ma waena o na aoao elua, a mahele ia ae la elua. Ike a pauʻaoʻao o ka triangle, akā, me ka ike ole kona mau kihi, e hiki ke 'imi i kekahi wahi i loko o kekahi alanui. E hana i kēia, e pono e imi i ka hapalua o ke anapuni. A laila, e huli mai, e lawe aku ai, mai keia i ka helu ana o kekahiʻaoʻao, a me ia eʻalo mai i ka eha loina i loaa mai ai. Next, huli i ka huinahalike kumu o ka helu i hele mai. hiki ke loaʻa ma ka hoonui a pauʻaoʻao, a me ka mahele ana i ka helu ma ka Area kākauʻia triangle ke kahahńnai o ka p ÷ ai i hoakakaia a puni ia, hoonuiia ka eha.

Ua ho'ākāka 'ia ka wahi o ka triangle like penei: hapalua o ke anapuni hoonuiia ma ke kahahńnai o ka p ÷ ai i ua kākauʻia ma loko o laila. Inā he triangle mea equilateral, hiki ke loaʻa kona wahi like penei:ʻaoʻao squaring, hoonui i ke kūpono huahelu ma ka huinahalike kumu o ekolu, alaila, e puunaue i ka helu ma ka eha. Like, e hiki e huli i ke kiekie o ka triangle, ma i nāʻaoʻao i like, no ka mea i kekahi o ia pono e hoonuiia e ka huinahalike kumu o ka ekolu, a laila, e puunaue i kēia helu e mau.

Theorems e pili pū ana i ka triangle

Ke kumu o theorems i hai aku ai i keia huahelu i ka Pythagorean theorem i ho'ākāka 'ia ma luna, ke theorem o sines a me cosines. Ka lua o ka (sine) mea i ina kekahiʻaoʻao i puunaueia e ka sine o ka huina e ku pono ana ia ia, he mea hiki ke loaa mai i ke kahahńnai o ka p ÷ ai i hoakakaia a puni ia, hoonuiia ka mau. Ke kolu (cosine) ka mea, ina o ka huina o na mika pāhoʻonui lua o kaʻaoʻaoʻelua, e lawe ia lakou me ka huina hoonui o ka elua manawa i ka cosine o ka huina, a aia ma waena o ka elua, e kiʻi i ke kolu o kaʻaoʻao o ka huinahalike.

Dali Triangle - aha ka ia?

He nui nā kanaka, ka wāʻalo me kēia manaʻo, ma mua, manao iho la ia i kekahi ano o ka ho'ākāka 'ana ma ka anahonua, akā,ʻaʻole ia mea pela. Dali Triangle - o ka inoa, he pono ole o ka ekolu wahi mea i pili loa i pili i ke ola o ka artist kaulana.
