Biraha laydhka ee laba geesoodka ah ayaa caadi ahaan loo adeegsadaa meelaha loo baahan yahay hagaajinta farsamada, sida nijaarnimada, biraha samaynta, iyo shaqada dhismaha. Naqshaddooda madaxa ee laba geesoodka ah ayaa ka dhigaysa in ay ku fududaadaan in lagu sugo aaladaha qulqulka, sida furaha ama furka qufulka, iyo in ay yartahay in ay jabaan marka loo eego naqshadaha kale ee madaxa. Furaha noocaan ah waxaa loo isticmaali karaa halka ay lagama maarmaan tahay si loo hubiyo hagaajin adag iyo halka adkeynta iyo dabacsanaanta joogtada ah loo baahan yahay
Shaqadeeda:
1. Hagaajinta Walxaha Saxan Fudud ee Dhismayaasha Fudud
2. Xoojinta iyo taageerada qaab dhismeedka dhismaha
