Step1: Comprobar razones de lados
Calculamos las razones de los lados correspondientes. $\frac{16}{8}=2$, $\frac{20}{10}=2$, $\frac{8}{4}=2$.
Step2: Comprobar ángulos
Los ángulos correspondientes son iguales: $\angle G = \angle C=114^{\circ}$, $\angle H=\angle B = 45^{\circ}$, $\angle I=\angle A=21^{\circ}$.
