Nyeredzi dzakashata: tsanangudzo uye zvinhu

Nechanhatu isiri yejometri ine zvikamu zvitatu zvakabatana nemitsetse isingarevi pamutsara mumwe chete wakarurama mu ndege. Mhedziso yechanhatu ndeye nheyo dziri pamucheto wemakona, uye mitsara inosangana navo inonzi mazhe ekatatu. Kuti uone nzvimbo yemunhu akadaro, kazhinji shandisa nzvimbo yechipfuva.

Kurongwa

Mukuwedzera kune zvidutu zvisinganzwisisi mativi, pane isosceles, kureva, ane mairi maviri akafanana. Ivo vanonzi lateral, uye rumwe rutivi ndiyo nheyo yemufananidzo. Ikoko kune rumwe rudzi rwema polygoni akadaro - equilateral. Zvose zvikamu zvitatu zvine urefu hwakafanana.

Nokuda kwetatu, kune chidimbu chechiyero chekuyera. Iyi mifananidzo inogona kunge yakasiyana-siyana, saka inotsanangurwa seiyi:

• Rectangular - ine angle ye 90 degrees. Mativi maviri ari pedo nekona iyi anonzi katetas, uye chechitatu - hypotenuse;
• Nyeredzi dzakagadzika dzinononoka nemakumbo ose akakomberedzwa asina kupfuura 90 degrees;
• Kunzwa-kutengesa - imwe kona huru kupfuura 90 degrees.

Tsanangudzo nemiganhu yekatatu

Sezvatatoona, denderedzwa imwe yemhando yemapurogoni ane maziso matatu uye nhamba yakafanana yemigwagwa yakarurama inovabatanidza. Taura mitsetse, sekutonga, zvimwechetezvo: maziso - mune zvinyorwa zvinyorwa zvechiLatini, uye mapoka akasiyana-siyana e-tsamba yakakura yakafanana.

Kana ukawedzera zvikamu zvose zvepatatu, unowana mukana we 180 degrees. Kuziva kona yemukati, unoda kubva pa 180 Degrees vanobvisa kukosha kwekona rekunze kwekona katatu. Kuti uwane kuti iyo yakajeka iri kunze yakaenzana, zvakakosha kuwedzera maviri akasiyana kubva mukati.

Mumakumbo mana matatu, ane majeko akaoma kana akavharidzirwa, zvakatarisana nekona huru ndiyo yakakura. Kana mitsara iri pakati pemiti yakafanana yakadaro, zvino, maererano, uye imwe neimwe yakaenzana nemadhora makumi matanhatu.

The triangle obtuse

Nzira yekuvhara kwechamutatu inogara yakakura kudarika 90-degree angle, asi pasi pechiratidzo chakaonekwa. Nokudaro, iyo yechipfuva yakabva kune 90 kusvika 180 degrees.

Mubvunzo unomuka: pane pane imwe nzvimbo yakagadzika mumunhu akadaro here? Mhinduro yacho iri pamusoro: kwete, nokuti nhamba yemakona inofanira kunge iri pasi pe 180 ⁰ . Kana mafungiro maviri ane, semuenzaniso, 95 degrees, ipapo chechitatu hachina nzvimbo.

Ma polygoni maviri akafukidzwa akaenzana akaenzana:

• Kana mativi ose maviri akaenzana uye chikamu pakati pavo chakaenzana;
• Kana rumwe rutivi uye rutivi rumwe rutivi rwakatarisana naro rwakaenzana;
• Kana mapoka matatu ezvinyorwa zvitatu akaenzana.

Zvinoshamisa mitsetse yenguva yekunze

Munzvimbo dzose dzakatarisana nemakumbo ekudzivirira, kune mitsetse inonzi inoshamisa. Chokutanga chazvo ndechekukwirira. Icho chirevo chechirevo kubva kune chimwe chemaziso kusvika kune rumwe rutivi. Zvose zvikomo zvinoputika pane imwe nzvimbo iyo inonzi inonzi chirevo. Mutsamba katatu ane angles obtuse, ichava kunze kwechimiro pachako. Kana ari emakona akacheka, nechepakati iri mune katatu pachayo.

Imwe mutsara ndeyemukati. Ichi chiito chakakonzerwa kubva kumusoro kusvika pakati penhare yakatarisana. Vese vevanamwari vanotendeuka muchetatu, uye nzvimbo yekuenzanisa kwavo ndiyo nzvimbo yekubwinya kweiyo polygon.

Bisectrix - mutsetse unoparadzanisa hafu yakafanana nemakumbo akavhara, uye vamwe vose. Kugadzikana kwemitambo mitatu yakadaro kunowanzoitika chete mumufananidzo pachayo uye kunotsanangurwa sepakati pechitenderedzwa chakanyorwa mudetatu.

Pakazoti, nheyo yedenderedzwa yakatsanangurwa pamusoro pechimiro ichi inogona kuwanikwa kubva pamatatu emapakati mukati. Aya ndiwo mitsetse yakasimwa kubva pakati pemigwagwa yakarurama inobatanidza zvikomo. Nzira inopindirana yezvikamu zvitatu zvepakati pepakati mumakatete matatu ane angles obtuse iri kunze kwechimiro.
