Qalabka isku-darka ayaa la barbar dhigayaa
oo lehisku darka la taaban karo ee meeraha.
Daab isku-darka ah wuxuu qaataa qaab-dhismeedka naqshadda parallelogram-ka. Marka kicinta ay si gaar ah u duusho, waxaa loo rogi karaa 180 darajo waxaana la sii wadi doonaa in dib loo isticmaalo. Daabku wuxuu yareeyaa kharashka qaybaha macaamiisha;
Gacanta isku-darka waxay qaadataa qaab-dhismeed nooca isku-xidhka ah si loo kordhiyo heerka isticmaalka daabyada.
Naqshad fudud oo gacanta isku-darka ah, yareynta fursadda gacanta warbixinta agabka, iyo naqshadeynta gogol u adkaysta xirashada oo leh wareejin si loo dheereeyo cimriga adeegga gacanta isku-darka.
[Isku-darka laba-geesoodka ah]
Qalabka isku qasidda waxa loo qaybiyaa laba nooc: nooca daab iyo nooca xarigga. Sababtoo ah cillado dhismeedkiisa iyo heerka isticmaalka yar ee daabku, gacanta isku qasidda waxay u baahan tahay in la beddelo ka dib muddo isticmaal ah.
Waxay ku xiran tahay qaab-dhismeedka [isku-darka laba-geesoodka ah]. Xaddidaaduhu waxay kordhiyaan suurtagalnimada in walxaha ay hayaan axalka iyo gacanta, taasoo kordhinaysa kharashka dayactirka macaamiisha iyo beddelka qaybaha.
Isbarbardhigga saamaynta isku-darka [Isku-darka shubka meeraha ee toosan] wuxuu buuxin karaa shuruudaha isku-darka ee shubka hore loo shubay, hufnaanta isku-darka sare, tayada isku-darka wanaagsan iyo buuxinta shuruudaha isku-darka badeecada.
Isbarbardhig [Isku-darka laba-geesoodka ah] Maadaama qaybta la diyaariyey si toos ah loogu diyaariyey saldhigga isku-darka, ma jirto isku-darka labaad ee gaadiidka booyadaha shubka ganacsiga, sidaa darteed heerka isku-dhafka ee hal walaaq ayaa looga baahan yahay inuu ka sarreeyo. Kaliya iyadoo la hagaajinayo isku-dhafka walaaqidda, heerka qashinka ee badeecada la dhammeeyay ayaa la dhimi karaa, tayada sare ee badeecada la dhammeeyeyna waa la gaari karaa. Sidaa darteed, waxqabadka sare ee isku-darka shubka shubka meeraha ee dhidibka toosan ayaa ku habboon shubka hore loo shubay marka loo eego [isku-darka shafka toosan ee laba-geesoodka ah].
Walaaq. [Isku-darka laba-geesoodka ah] wuxuu ku habboon yahay soo saarista shubka ganacsiga ee mugga sare leh iyo qaar
