Kama sharudda na triangles: da ra'ayi da kuma ikon yinsa,

An muhimmanci ra'ayi a lissafi a matsayin kimiyya, ne kama daga Figures. Ilimi na irin kaddarorin yale mu mu shirya mai girma yawan ayyuka, ciki har da a hakikanin rai.

Concepts

Similar siffofi ne wadanda cewa za a iya tuba a cikin juna da halitta dukkan bangarorin da wani factor. Cikinsa Game da kusassari ya zama daidai.

Bari mu bincika a cikin mafi daki-daki cikin alamun kama daga triangles. Akwai uku dokoki da damar mu mu tabbatar da cewa wadannan Figures da wannan dukiya.

A farko alamar kama triangles bukatar cewa daidaici na biyu nau'i-nau'i daga m kusassari.

A cewar wani biyu mulki, kyan gani, Figures suna dauke da irin wannan a lokacin da bangarorin biyu na Game da segments ne na gwargwado ga sauran. A kusassari wanda aka kafa ta su, ya zama daidai.

Kuma a karshe, ta uku ãyã: da triangles ne irin wannan idan duk sãsanninsu ne na gwargwado.

Akwai wasu alkaluma cewa a wasu kaddarorin za a iya dangana ga wani takamaiman irin (equilateral, isosceles, rectangular). Domin yabo, irin triangles ne irin wannan, dole ne ka yi m yanayi. Muna da misali, ka yi la'akari da kama daga cikin alamun da wani rectangular triangles:

1. hypotenuse da kuma daya daga cikin kafafu daya gwargwado ga m bangarorin da sauran.
2. wani m kwana na daya adadi ne guda a cikin sauran.

Idan ka tsayar da ãyõyin kama triangles, dole mu da wadannan Properties:

1. rabo na mikakke abubuwa (medians, bisectors, Heights, perimeters) daidaita da coefficient na kama.
2. idan ka sami sarari rarraba sakamakon, mun samu square daga wannan lambar.

A bisa Properties ƙyale mu mu shirya wata babbar lamba na lissafi matsaloli. Suna amfani da ko'ina a hakikanin rai. Sanin ãyõyin kama daga triangles, za ka iya sanin ko tsawo na wani abu ko yin lissafi da nisa zuwa m batu.

Don gano, misali, da tsawo daga wata itãciya, a kan wani pre-auna nesa kafa tsaye iyakacin duniya a kan abin da aka gyarawa da juyawa madauri. An daidaitacce zuwa abu da kuma saman lamba a kan ƙasa da ma'ana inda line, ci gaba da shi intersects a kwance surface. Mun samu irin wannan dama-angled triangles. Da aunawa da nesa daga wani batu da iyakacin duniya, sa'an nan zuwa ga abu, mun sami kama coefficient. Sanin tsawo na iyakacin duniya, zaka iya lissafta wannan siga ga itace.

Don samun da nisa tsakanin biyu da maki a cikin ƙasa to zabi wani jirgin sama. Sa'an nan mataki da nisa daga shi zuwa samuwa. Gama dukan dige a ƙasa, kuma auna kusassari da suke dab da sanannun gefe. By gina irin wannan alwatika a kan takarda da kuma kayyade rabo daga cikin bangarorin biyu Figures, sauƙi lissafta da nisa tsakanin maki.

Saboda haka, alamun kama triangles - daya daga cikin mafi muhimmanci Concepts na lissafi. An yadu amfani ba kawai domin gudanar da bincike dalilai, amma kuma ga sauran dalilai.
