A pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric.

Kuj paub, dab tsi yog qhov kev sib koom ua pov thawj hauv geometry?

Cov ua pov thawj yog a pov thawj ntawm a geometric theorem uas siv cov ntsiab lus "generalized" ntawm Cartesian Plane los ua kev sib cav. Cov txheej txheem feem ntau yog muab cov hloov pauv rau cov ua haujlwm ntawm ib lossis ntau cov ntsiab lus, thiab tom qab ntawd siv cov kev hloov pauv no hauv cov qauv nruab nrab lossis qhov nrug deb.

Ib tug kuj yuav nug, dab tsi pov thawj siv cov duab? A pov thawj uas siv cov duab ntawm ib lub dav hlau coordinate rau ua pov thawj geometric zog yog hu ua trigonometric.

Kuj Paub, qhov piv txwv ua pov thawj yog dab tsi?

Hauv ib ua pov thawj , koj tab tom ua pov thawj cov lus geometric siv algebra thiab cov koom tes dav hlau. Ib txhia piv txwv ntawm cov lus koj tuaj yeem ua pov thawj nrog a ua pov thawj yog: Ua pov thawj los yog tsis lees paub tias cov plaub fab uas txhais los ntawm cov ntsiab lus egin{align*}(2, 4), (1, 2), (5, 1), (4, -1)end{align*} yog parallelogram.

Koj ua pov thawj li cas daim duab peb sab isosceles ntawm daim duab?

Cov kauj ruam los ua pov thawj

  1. npaj 3 ntsiab lus (yeem)
  2. siv tus qauv nyob deb los xam qhov ntev ntawm txhua sab ntawm daim duab peb sab.
  3. Yog tias 2 sab muaj qhov sib npaug ntawm sab, ces daim duab peb sab yog isosceles.
