a, b, c, d - măsurile unghiurilor ⇒ a+b+c+d= 360°

$\it \{a,b, c, d\}\ d.p. \{2,3, 6, 7\} \Rightarrow \dfrac{a}{2}= \dfrac{b}{3}= \dfrac{c}{6} =\dfrac{d}{7}= \dfrac{a+b+c+d}{2+3+6+7} =
\\ \\ \\ 
= \dfrac{360^0}{18} =20^0$

$\it \dfrac{a}{2} =20^0 \Rightarrow a=20^0\cdot2 =40^0
\\ \\
\dfrac{b}{3} =20^0 \Rightarrow b=20^0\cdot3 =60^0
\\ \\
\dfrac{c}{6} =20^0 \Rightarrow c=20^0\cdot6 =120^0
\\ \\
\dfrac{d}{7} =20^0 \Rightarrow d=20^0\cdot7 =140^0$
