Polygon. A kaw lub dav hlau daim duab nrog tsawg kawg peb sab uas yog ntu. Cov sab sib tshuam tsuas yog ntawm lawv qhov kawg nkaus thiab tsis muaj ob qhov nyob ib sab sab yog collinear. Thevertices ntawm lub polygon yog qhov kawg ntawm qhov sab.
Tom qab ntawd, ib tus tuaj yeem nug, dab tsi yog daim duab kaw nrog peb lossis ntau sab?
Ib qho yooj yim, kaw dav hlau daim duab tsim los ntawm peb los yog ntau tshaj kab ntu sib ntsib tsuas yog ntawm lawv qhov kawg ntawm qhov kawg hu ua polygon. Polygons muaj npe raws li tus naj npawb ntawm sab . Ib tug tsis tu ncua polygon muaj tag nrho sab congruent thiab tag nrho cov ces kaum congruent. Lub vertex ntawm ib tug polygon yog qhov twg sab ntsib.
Kuj Paub, dab tsi yog qhib thiab kaw cov nuj nqis? Ib qhib cov duab yog tsim los ntawm kab ntu, tab sis muaj tsawg kawg yog ib kab ntu uas tsis txuas nrog dab tsi ntawm ib qho ntawm nws qhov kawg. Yog tias ib daim duab yog nyob rau ntawm txhua sab-rau-kawg thiab tsim ib daim duab tsis muaj qhov qhib yog hu ua a kaw puab.
Kuj paub, lub dav hlau kaw yog dab tsi?
dav hlau daim duab. Nws yog ib daim duab tiaj tus. Nws tuaj yeem yog kaw los tsis kaw . polygon. A kaw dav hlau daim duab uas yog ua los ntawm peb lossis ntau ntu.
Dab tsi polygon muaj 5 vertices thiab 3 sab?
Ib pentagon muaj 5 kaum sab xis, 5 paj thiab 5 lus . Qhov no yog ib hexagon.

Dab tsi yog equidistant los ntawm peb sab ntawm daim duab peb sab?
Lub ntsiab lus uas sib npaug rau txhua sab ntawm daim duab peb sab yog hu ua incenter: Ib qho nruab nrab yog ib qho kab uas muaj ib qho ntawm nws qhov kawg ntawm lub vertex ntawm daim duab peb sab thiab lwm qhov kawg ntawm qhov nruab nrab ntawm sab opposite lub vertex. Peb qhov nruab nrab ntawm ib daim duab peb sab sib ntsib hauv centroid
Peb tus yam ntxwv dav dav ntawm cov hlau yog dab tsi?
Peb yam ntxwv ntawm cov hlau yog lawv cov conductivity zoo, malleability, thiab ci iab tsos. Cov hlau yog cov zoo conductors ntawm tshav kub thiab hluav taws xob
Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Lub voj voog puas yog lub dav hlau kaw?
Nws txawv ntawm cov duab uas tau pom yav dhau los. Nws yog hu ua lub voj voog. Ib lub voj voog yog aplane kaw daim duab uas nyob rau hauv ib tug nkhaus, tsis muaj ob sab thiab tsis muaj kaum (vertex)
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
