Aragtida Baytagoras

Xisaab ahaan, aragtida Baytagoras ama qaybta Baytagoras waa odhaah ku saabsan dhinacyada saddexagalka saxda ah.

Aragtida Baytagoras
Wadarta meelaha labada geesood ee lugaha (a iyo b) waxay la mid yihiin bedka labajibbaaran ee hibotenuus (c).

Caddaynta Leonardo da Vinci.

Noocyada kale ee aragtida

Haddii c ay muujiso dhererka hibotenuus iyo a iyo b waxay tilmaamayaan labada dherer ee lugaha ee saddexagalka saxda ah, markaa aragtida Baytagoras waxaa lagu muujin karaa aragtida Baytagoras:

$a^{2}+b^{2}=c^{2}$

Haddii kaliya dhererka lugaha saddexagalka saxda ah la yaqaan laakiin aan la garanayn hibotenuus, markaa dhererka hibotenuus waxaa lagu xisaabin karaa aragtida

$c={\sqrt {a^{2}+b^{2}}}$

Haddii dhererka hibotenuus iyo hal lug la yaqaan, markaa dhererka lugta kale waxaa loo xisaabin karaa sida

$a={\sqrt {c^{2}-b^{2}}}$

ama

$b={\sqrt {c^{2}-a^{2}}}$
