Mubhuku rino, tichaona kuti dhigirii chiyero chekona chii, nezvainopimwa. Isu tinopawo pfupiso yenhoroondo yenyaya iyi.
Kutsunga kwedhigirii chiyero chekona
Beam kutenderera huwandu AO kumativi dot O akadana chiyero chekona.
Dhigirii chiyero chekona - nhamba yakanaka inoratidza kangani dhigirii uye zvikamu zvayo (miniti nechipiri) zvinokwana mukona iyi. Avo. ndiyo nhamba yese yemadhigirii, maminetsi, uye masekonzi pakati pemativi ekona.
Angle - ichi chimiro chejometri, icho chinoumbwa nemaviri anobuda kubva pane imwe nzvimbo (ndiyo vertex yekona).
Side angle ndiwo maranzi anoumba kona.
Angle units
dhigirii - iyo yakakosha chikamu chekuyera kwemakona endege mujometri, yakaenzana ne1/180 yekona yakatwasanudzwa. Zvinonzi "°".
Mineti iri 1/60 yedhigirii. Chiratidzo chinoshandiswa kuratidza'".
Chepiri iri 1/60 yeminiti. Zvinonzi "''".
mienzaniso:
- 32 ° 12′ 45 ″
- 16 ° 39′ 57 ″
Chishandiso chakakosha chinowanzo shandiswa kuyera makona - protractor.
Ipfupi nyaya
Kutaurwa kwekutanga kwechiyero chedhigirii kunowanikwa muBabironi Yekare, umo iyo sexagesimal nhamba system yakashandiswa. Masayendisiti enguva iyoyo akakamura denderedzwa kuita 360 madhigirii. Zvinotendwa kuti izvi zvakaitwa nekuda kwekuti kune mazuva anosvika mazana matatu nemakumi matanhatu mugore rezuva, kutamiswa kweZuva zuva nezuva pamwe neiyo ecliptic uye zvimwe zvinhu zvakaverengerwawo. Mukuwedzera, zvaive nyore kuita masvomhu akasiyana-siyana.
