Ib ob peb yam piv txwv ntawm cov polygons tsis tu ncua polygons Ib txwm hexagon txhais tau tias yog hexagon uas yog ob qho tib si thiab sib npaug. Nws yog bicentric, txhais tau hais tias nws yog ob qho tib si cyclic (muaj ib lub voj voog ncig) thiab tangential (muaj ib lub voj voog inscribed). lub sij hawm apothem (lub vojvoog ntawm lub voj voog inscribed). Tag nrho cov kaum sab hauv yog 120 degrees. https://en.wikipedia.org › wiki › Hexagon

yog ib daim duab peb sab, quadrilateral, pentagon, hexagon, heptagon heptagon A heptagon muaj xya lub kaum sab hauv uas suav nrog 900 ° thiab xya lub kaum sab nrauv uas suav nrog 360 °. Qhov no muaj tseeb rau ob qho tib si tsis tu ncua thiab tsis xwm yeem heptagons. Nyob rau hauv ib txwm heptagon, txhua lub kaum sab hauv yog kwv yees li 128.57 °. https://tutors.com › lej-tutors › geometry-help › heptagon

Yuav ua li cas polygon nrog piv txwv?
Definition of Regular Polygon. Ib tug polygon uas muaj tag nrho cov sab sib npaug yog tag nrho cov polygons tsis tu ncua. Txij li tag nrho cov sab ntawm lub polygon yog sib npaug, yog li ntawd tag nrho cov ces kaum ntawm ib tug tsis tu ncua polygon yog sib npaug. Cov piv txwv feem ntau ntawm cov polygons tsis tu ncua yog square, rhombus, daim duab peb sab sib npaugetc.
Yuav ua li cas yog lub polygon ib txwm?
Ib tug polygon tsis tu ncua thaum txhua lub ces kaum sib npaug thiab txhua sab sib npaug (txwv tsis pub nws yog "tsis xwm yeem"). Nov yog tsis tu ncua pentagon (ib 5-sided polygon). Saib: Polygon. Lub Pentagon tsis tu ncua.
7 sab zoo li cas hu ua?
In geometry, a heptagon is a xya-sided polygon or 7-gon.
Yuav ua li cas thiaj tsis raug tus kab mob hu ua?
Polygon Shape. Cov duab muaj rau sab, yog li peb paub peb hu nws hexagon. Nws yog ib qho yooj yim kom pom tias ob sab ntawm cov duab tsis yog txhua tus muaj qhov sib npaug ntev, yog li nws yog ib qho tsis xwm yeem polygon. Yog li, peb xav hais tias cov duab yog qhov tsis xwm yeem hexagon.
