Similarity ana hoʻohālike o triangle mauna: ka manaʻo a me ka laulā

An nui manaʻo ma ka anahonua like me ka 'epekema, ka aʻo Kīwala'ō o huahelu. Knowledge o ia mau waiwai e leie aku mākou e hoʻoponopono i ka nui helu o ka hana, a me ka maoli ola.

manaÿo

Similar kinona i ka poe i hiki ke hoohuliia mai i loko o kekahi i kekahi, ma ka hoonui a pauʻaoʻao ma ka kekahi ololi. Ma ke aha ka lakou mau pana pua e e like.

E mākou noʻonoʻo i oi au mamuli o ka hoailona o ka similarity o triangle mauna. Aia i ekolu rula e ae mai, e hoʻike ia mau kii i keia waiwai.

Ka mua hoailona o ka like triangle mauna pono i ka like o na hui elua o like pana pua.

E like me ia i ka lua o ka rula, nānā akula au i na kii i manaoia i 'ano like ka wā o nāʻaoʻaoʻelua o ka lakou mau Hoʻohana i hapaʻauhau i ka mea' ē aʻe. I ka pana pua i i hanaʻia e ia, e like.

A eia ka mea hope, ke kolu o ka hoailona: na triangle mauna e like ina kā lākou mauʻaoʻao a pau i hapaʻauhau.

Aia nō kekahi mau kii i loko o kekahi mau waiwai hiki e wahi ana i kekahi mau 'type (equilateral, isosceles, huinahń). No ka apono, ua triangle mauna i like, e hana'emi ana. Mākou i no ka laʻana, noonoo aʻo Kīwala'ō o na hoailona o ka huinahń loa triangle mauna:

1. hypotenuse a me kekahi o na wawae o kekahi hapaʻauhau i ka like aoao o ka mea'ē aʻe;
2. kekahi huʻi huina o kekahi huahelu o ka ia i loko o ka 'ē aʻe.

Inā 'oe e malama i na hoailona o ka like triangle mauna, mākou i ka keia mau waiwai:

1. lākiō o ka laina oihana mua (Media, bisectors, kiekie, anapuni) like i ke kaʻi lau waiwai o ka similarity;
2. ina oe e huli i wahi ka mahele ana i ka hopena, ua loaa i ka huinahalike o keia helu.

Ka luna waiwai ae mākou e hoʻoponopono i ka nui helu o geometric pilikia. Ka mea, e hoʻomano hoʻohana i maoli ke ola. Ike ana i na hoailona o ka similarity o triangle mauna, e hiki ke hoʻoholo i ke kiekie o kekahi mea paha, e ho omaulia i ka mamao i ke keʻena wahi.

E imi i mai, no ka mea hoike, i ke kiekie o ka laau, ma kahi loihi mālama '-ana i hoʻopapakū laau ma i ua paa i ka kaʻapuni kaula. Ua Ua aʻo i kaʻoihana i ka mea a me ka luna hoailona ma ka honua i ka wahi ma ka laina, hoʻomau ka mea intersects ka papamoe ili. E loaa like akau-huina triangle mauna. Ana i ka mamao mai ka wahi a hiki i ka laau, a laila, i ka mea, ua loaʻa similarity kaʻi lau waiwai. Ike i ke kiekie o ka laau, e hiki eaaei e huli i ka ia aiao no ka laau.

E huli i ka mamao ma waena o nā heluʻai i loko o ka'āina, e koho i kekahi pelane. A laila, ana i ka mamao mai ka mea i loaʻa. Hoʻohui i nā kiko kona kiʻi ma luna o ka honua, a ana i ka pana pua i mea e pili ana i kaʻaoʻao maikaʻi-ike. Ma ka kūkulu ia i ka triangle ma ka pepa a me ka hoomaopopo ana i ka lākiō o nāʻaoʻao o nā huahelu, eaaei compute i ka mamao ma waena o ka papa.

Penei, na hoailona o ka like triangle mauna - kekahi o ka loa nui manaÿo o ka anahonua. Ua Ua hoʻomano hoʻohana ole wale no ka noiʻi hana, akā, no hoi no na hana.
