Satz des Pythagoras: $a^2+b^2=c^{2}a^2+b^2=c^2$

$h^2=s^2-{\left({\displaystyle \frac{a}{2}}\right)}^{2}h^2=s^2-\backslash left(\backslash dfrac\{a\}\{2\}\backslash right)^2$ oder $h^2=k^2+{\left({\displaystyle \frac{a}{2}}\right)}^{2}h^2=k^2+\backslash left(\backslash dfrac\{a\}\{2\}\backslash right)^2$

Sinus: $\sin (\alpha )={\displaystyle \frac{\text{Gegenkathete}}{\text{Hypotenuse}}}\backslash sin\; (\backslash alpha\; )=\backslash dfrac\{\backslash text\{Gegenkathete\}\}\{\backslash text\{Hypotenuse\}\}$

$\sin (\alpha )={\displaystyle \frac{k}{s}}\backslash sin(\backslash alpha)=\backslash dfrac\{k\}\{s\}$

Tangens: $\tan (\beta )={\displaystyle \frac{\text{Gegenkathete}}{\text{Ankathete}}}\backslash tan\; (\backslash beta\; )=\backslash dfrac\{\backslash text\{Gegenkathete\}\}\{\backslash text\{Ankathete\}\}$

$\tan (\beta )={\displaystyle \frac{k}{{\displaystyle \frac{a}{2}}}}\backslash tan(\backslash beta)=\backslash dfrac\{k\}\{\backslash dfrac\{a\}\{2\}\}$
