Rütj (Geometrii)

Tekst üüb Öömrang

En Rütj as en sjauerhuk mä likelung sidjen, diar oober (normoolerwiis) ei luadrocht tu enööder stun. Wan jo luadrocht stun, do as det Rütj en Kwadroot.

En rütj mä
• huken A, B, C, D
• likelung sidjen a, b, c, d
• winkler α = γ, β = δ
• hööchde h_a = h_b
• diagonaalen e, f

Areal	$A=a\cdot h_{a}$
	$A={\frac {e\cdot f}{2}}$
	$A=a^{2}\cdot \sin(\alpha )=a^{2}\cdot \sin(\beta )$
	$A={\frac {h_{a}^{2}}{\sin(\alpha )}}={\frac {h_{a}^{2}}{\sin(\beta )}}$
