Wzór	P=ab/2	V= 1/3٠Pp٠H	P=(a+b)٠h/2	S=at2/2
Wyznaczana wielkość	b	H	a	t
Przekształcony wzór	b=2P/a	H=3V/Pp	a=2P/h -b	t=√(2S/a)

$P=\frac{ab}{2}\mid \cdot 2$  

$2P=ab\mid :a$  

$b=\frac{2P}{a}$  


$V=\frac{1}{3}\cdot P_p\cdot H\mid \cdot 3$  

$3V=P_p\cdot H\mid :P_p$  

$H=\frac{3V}{P_p}$  


$P=\frac{\left(a+b\right)\cdot h}{2}\mid \cdot 2$  

$2P=\left(a+b\right)\cdot h\mid :h$  

$\frac{2P}{h}=a+b\mid -b$  

$a=\frac{2P}{h}-b$  



$S=\frac{a{t}^2}{2}\mid \cdot 2$  

$2S=a{t}^2\mid :a$  

$t^2=\frac{2S}{a}$  

$t=\sqrt{\frac{2S}{a}}$
