Explanation:

Step1: Identificar ángulos congruentes

Como se da que $\angle1\cong\angle2$ y $\angle3\cong\angle4$, la razón es el Teorema de Ángulos Verticales (ya que ángulos verticales son congruentes).

Step2: Aplicar propiedad de sustitución

Dado que $m\angle1 + m\angle4=180^{\circ}$ y $m\angle1 = m\angle2$, $m\angle3 = m\angle4$, sustituyendo obtenemos $m\angle2 + m\angle3=180^{\circ}$.

Answer:

La razón para $\angle1\cong\angle2$ y $\angle3\cong\angle4$ es el Teorema de Ángulos Verticales. La razón para la fila con la propiedad de sustitución es aplicar la igualdad de medidas de ángulos congruentes en la ecuación $m\angle1 + m\angle4 = 180^{\circ}$.
