Nyob rau hauv txhua daim duab peb sab, lub centroid, circumcenter andorthocenter ib txwm pw ntawm ib tug ncaj kab , npe Euler kab . Sim no Drag tej txiv kab ntxwv dot ntawm ib tug vertex ntawm daim duab peb sab. Peb lub dots sawv cev rau peb lub chaw yuav ib txwm nyob ntawm ntsuab Euler kab.
Ua li no, Euler kab tsim li cas?
Qhov chaw ntawm lub centroids ntawm equilateral trianglesinscribed nyob rau hauv ib daim duab peb sab muab yog tsim los ntawm ob kab perpendicular rau daim duab peb sab muab Eulerline.
Euler ntu yog dab tsi? Euler Kab. Cov kab ntu uas hla ib daim duab peb sab lub orthocenter, centroid, andcircumcenter.
Hauv qhov no, cov ntsiab lus twg nyob ntawm Euler kab?
Euler Kab . Cov kab ntawm qhov twg theorthocenter, daim duab peb sab centroid, circumcenter, de Longchamps taw tes , cuaj- taw tes center, thiab ib tug xov tooj ntawm lwm yam tseem ceeb daim duab peb sab chaw dag.
Dab tsi yog kab nyob nruab nrab ntawm daim duab peb sab hu ua?
A kab txuas ib vertex ntawm lub daim duab peb sab mus rau qhov nruab nrab ntawm qhov opposite sab yog hu ua amedian cov daim duab peb sab . Cov medians ntawm no daim duab peb sab yog AA', BB', CC', thiab lawv muaj xim ntsuab. Daim ntawv ceeb toom tias lawv txhua tus ntsib ntawm ib qho G hauv qhov daim duab peb sab , kuj xim ntsuab. Qhov no yog hu ua lub centroid daim duab peb sab.
