Hauv geometry, a golden duab plaub yog ib tug uas nws sab lengths nyob rau hauv lub golden piv (kwv yees 1:1.618).
Kuj paub, qhov piv ntawm cov duab plaub golden yog dab tsi?
Kwv yees li ntawm 1: 1.61 piv , cov Golden Ratio tuaj yeem ua piv txwv siv a Golden Rectangle . Qhov no yog ib duab plaub qhov twg, yog tias koj txiav tawm ib square (sab ntev sib npaug rau sab shortest ntawm lub duab plaub ), cov duab plaub uas yog sab laug yuav muaj tib proportions li tus thawj duab plaub.
Tom qab, lo lus nug yog, dab tsi yog qhov ntev ntawm ib daim duab plaub zoo meej? A duab plaub uas tuaj yeem tsim los ntawm squares txhua qhov sib txawv qhov ntau thiab tsawg hu ua zoo tag nrho . Tus naj npawb ntawm cov duab plaub zoo meej ntawm kev txiav txim 8, 9, 10, yog 0, 2, 6, 22, 67, 213, 744, 2609, (OEIS A002839) thiab cov lej sib raug ntawm cov tsis zoo duab plaub 0, 1, 0, 0, 9, 34, 103, 283, Nyob rau hauv no hais txog, koj yuav ua li cas nrhiav tau qhov ratio ntawm ib daim duab plaub?
Teeb tsa a piv qhov twg koj sab loj yog nyob rau sab saum toj ntawm feem thiab lub me me yog nyob rau hauv qab ntawm feem. Hauv qhov piv txwv, 8 nti / 4 nti. Faib cov piv , ces teem tus lej hauv qab rau ib qho. Hauv qhov piv txwv, 8 faib los ntawm 4 sib npaug 2.
Yuav ua li cas koj ua ib daim duab plaub zoo meej?
Ib lub duab plaub golden tuaj yeem tsim nrog tsuas yog ib qho ncaj nraim thiab lub compass hauv plaub kauj ruam yooj yim:
- Kos ib lub square yooj yim.
- Kos ib kab los ntawm nruab nrab ntawm ib sab ntawm lub xwmfab mus rau lub kaum sab xis.
- Siv cov kab ntawd ua lub vojvoog los kos ib qho arc uas txhais qhov siab ntawm daim duab plaub.
- Ua kom tiav cov duab plaub golden.

Dab tsi yog qhov txawv ntawm daim duab thiab daim duab?
Ib daim duab yog ib daim duab ntawm kev ua lej, tab sis kuj siv tau (loos) txog ib daim duab ntawm cov ntaub ntawv txheeb cais.A daim duab yog ib daim duab sawv cev ntawm cov ntaub ntawv, qhov twg ib kab ntawv yog ib daim ntawv
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
Dab tsi yog qhov zoo thiab qhov tsis zoo hauv daim duab?
Cov duab zoo yog cov duab ntawm cov khoom tiag tiag (xws li lub qhov rais ncej). Cov duab tsis zoo yog qhov chaw nyob nruab nrab ntawm cov khoom (xws li qhov chaw nyob hauv lub qhov rais ncej)
Qhov twg ntawm cov plaub hau plaub hau yog ib txwm plaub hau plaub hau?
square Tsis tas li ntawd nug, qhov ntsuas ntawm ib lub quadrilateral tsis tu ncua yog dab tsi? Yog, sab hauv lub kaum sab xis ntawm txhua lub ces kaum ntawm ib lub quadrilateral tsis tu ncua yog txhua 90 degrees (360 degrees / 4 fab).
Dab tsi yog qhov zoo sib xws ntawm daim ntawv qhia thiab daim duab?
Yog li koj tuaj yeem hais tias, qhov txawv yog tias daim duab qhia chaw yog qhov sawv cev ntev ntev ntawm kev sib raug zoo spatial, thiab cov duab yog cov ntaub ntawv ntawm qhov xwm txheej ntawm ib qho tshwj xeeb. Vam tias qhov no yuav pab tau koj
