Hauv geometry a khov kho muaj muaj nyob hauv ib lub dav hlau . A dav hlau txhais tau tias yog lub tiaj tus thiab ob sab saum npoo uas txuas mus rau infinitely. Cov lus tseeb yog - Hauv geometry, a khov kho muaj muaj nyob rau hauv peb-dimensional qhov chaw. Hauv geometry, 3d duab muaj qhov tob, dav thiab qhov siab.
Ua raws li qhov xav tau, lub dav hlau muaj pes tsawg qhov ntev?
Lub dav hlau yog ib lub tiaj tiaj uas tsis muaj thickness. Peb lub ntiaj teb muaj peb qhov ntev , tab sis tsuas muaj ob qhov ntev ntawm ib lub dav hlau: ntev thiab dav ua ib lub dav hlau.
Tsis tas li ntawd, dab tsi yog qhov piv txwv ntawm lub neej tiag tiag ntawm lub dav hlau hauv geometry? Piv txwv tuaj yeem yog daim duab peb sab, squares, duab plaub, kab, voj voog, cov ntsiab lus, pentagons, nres cov paib (octagons), thawv (prisms, lossis tsuav (cubes). Piv txwv ntawm lub dav hlau yuav yog: lub desktop, chalkboard / whiteboard, ib daim ntawv, ib lub TV screen, qhov rais, phab ntsa los yog ib lub qhov rooj.
Ib yam li ntawd, nws raug nug, puas yog hexagon ca lossis khoom?
Nco ntsoov, txhua lub ntsej muag yog a dav hlau puab. Hauv daim duab no, lub hauv paus, lossis sab saum toj thiab hauv qab, yog hexagons thiab ob sab yog tag nrho cov duab plaub. Muaj rau lub ntsej muag nyob ib ncig ntawm ob sab thiab ob lub hauv paus.
Dab tsi yog dav hlau thiab khoom geometry?
Dav hlau Geometry yog hais txog cov duab tiaj tus zoo li cov kab, lub voj voog thiab cov duab peb sab uas tuaj yeem kos rau ntawm daim ntawv. Khoom Geometry yog hais txog peb yam khoom xws li lub voos xwmfab, prisms, cylinders thiab spheres.

Koj puas tuaj yeem txheeb xyuas lub luag haujlwm uas cov neeg tsim khoom ua si hauv lub voj voog carbon?
Cov neeg tsim khoom, cov neeg siv khoom, thiab cov decomposers ua lub luag haujlwm hauv lub voj voog carbon? ~ Cov neeg tsim khoom tsim lawv cov khoom noj los ntawm kev ua kom zoo nkauj siv lub zog los ntawm lub hnub ci thiab carbon dioxide los ntawm huab cua. Lawv ua pa rov qab carbon dioxide rau hauv qhov chaw. Cov neeg siv khoom siv cov khoom noj uas tsim los ntawm cov neeg tsim khoom rau lub zog
Cov khoom puas tuaj yeem muab cais ua cov khoom yooj yim?
Cov ntsiab lus tsis tuaj yeem tawg mus rau hauv cov khoom yooj yim. Ib yam li ntawd, ib lub ntsiab lus tsis tuaj yeem hloov pauv mus rau hauv ib lub caij sib txawv. Cov khoom siv tshuaj yog qhov yooj yim ntawm cov khoom
Dab tsi pov thawj siv cov duab ntawm lub dav hlau sib koom ua pov thawj cov khoom geometric?
Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric
Muaj pes tsawg quadrants nyob rau hauv lub dav hlau Cartesian?
plaub Ua li no, plaub lub quadrants ntawm lub dav hlau ua haujlwm yog dab tsi? Cov kev sib tshuam x- thiab y-axes faib cov tswj lub dav hlau rau hauv plaub ntu. Cov no plaub ntu hu ua quadrants . Quadrants muaj npe siv cov lej Roman I, II, III, thiab IV pib nrog rau sab xis quadrant thiab txav counterclockwise.
Lub dav hlau sib koom ua ke tuaj yeem pab koj txiav txim siab li cas cov tog neeg sib koom ua ke?
Muab ob daim duab peb sab ntawm lub dav hlau sib koom ua ke, koj tuaj yeem tshawb xyuas seb lawv puas sib haum los ntawm kev siv cov qauv nyob deb kom pom qhov ntev ntawm lawv sab. Yog hais tias peb khub ntawm sab yog congruent, ces daim duab peb sab yog congruent los ntawm saum toj no theorem
