Txoj Kev Tshiab Rau Pobzeb Koj Pem teb ( Yog Koj Zoo li Pentagons ) Tsis tu ncua hexagons ua haujlwm, ib yam nkaus, tab sis tsis yog a tsis tu ncua pentagon . Qhov teeb meem nrog a tsis tu ncua pentagon (tag nrho cov sab tib lub ntev thiab tag nrho cov sab hauv lub kaum sab xis tib yam) yog hais tias lub sab hauv lub kaum sab xis ntawm tej vertex yog 108 degrees.

Ua kom pom qhov no, koj puas tuaj yeem ua cov nplais pentagons?

Hauv geometry, a pentagonal pobzeb yog a pobzeb ntawm lub dav hlau uas txhua tus neeg ib feem yog nyob rau hauv cov duab ntawm ib pentagon . A tsis tu ncua pentagonal tiling ntawm lub dav hlau Euclidean yog tsis yooj yim sua vim hais tias lub sab hauv lub kaum sab xis ntawm a tsis tu ncua pentagon , 108 °, tsis yog divisor ntawm 360 °, lub kaum sab xis ntsuas ntawm tag nrho tig.

vim li cas pentagons tsis tu ncua tessellate? Yuav kom a tsis tu ncua polygon rau tessellate vertex-rau-vertex, lub kaum sab hauv ntawm koj lub polygon yuav tsum faib 360 degrees tusyees. Los ntawm 108 tsis faib 360 tusyees, lub tsis tu ncua pentagon tsis tessellate txoj kev no. Koj tuaj yeem pom tias cov ces kaum ntawm tag nrho cov polygons nyob ib ncig ntawm ib qho vertex sum rau 360 degrees.

Raws li txoj cai, pentagons puas tuaj yeem ua ke?

Daim duab peb sab, squares thiab hexagons yog cov duab tsis tu ncua uas tessellate los ntawm lawv tus kheej. Koj ua tau muaj lwm yam tessellations ntawm cov duab tsis tu ncua yog tias koj siv ntau tshaj ib hom duab. Koj ua tau txawm tessellate pentagons , tab sis lawv yuav tsis yog ib txwm muaj. Rau daim duab peb sab ua ib hexagon.

Puas yog tag nrho cov polygons tessellate?

Equilateral daim duab peb sab, squares thiab tsis tu ncua hexagons yog tib yam li niaj zaus polygons uas yuav tessellate . Yog li ntawd, muaj yog tsuas yog peb yam tsis tu ncua tessellations . 3.
