Step1: Dado que $\angle WVX\cong\angle IHX$
Esto es una premisa dada.
Step2: Dado que $m\angle IHX + m\angle QST=180^{\circ}$
Esto se basa en un teorema (probablemente ángulos adyacentes suplementarios o un teorema de líneas paralelas).
Step3: Sustitución
Como $\angle WVX\cong\angle IHX$, entonces $m\angle WVX = m\angle IHX$. Sustituyendo $m\angle IHX$ por $m\angle WVX$ en la ecuación $m\angle IHX + m\angle QST = 180^{\circ}$, obtenemos $m\angle WVX + m\angle QST = 180^{\circ}$.
