Question
statements reasons
- \\(l \parallel n\\) given
- \\(m\angle 3 + m\angle 4 = 180^{\circ}\\)
- \\(m\angle \box + m\angle 5 = 180^{\circ}\\)
- \\(m\angle 3 + m\angle \box = m\angle 8 + m\angle 5\\)
- \\(\angle 4 \cong \angle 8\\)
- \\(m\angle \box = m\angle 8\\) definition of congruent angles
- \\(m\angle 3 + m\angle \box = m\angle 8 + m\angle 5\\)
- \\(m\angle 3 = m\angle 5\\) subtraction property of equality
- \\(\angle 3 \cong \angle 5\\) definition of congruent angles
Identificar la justificación para la afirmación 2
$$
\text{Afirmación 2: } m\angle3 + m\angle4 = 180^\circ \implies \text{Razón: Linear Pair Postulate}
$$
Determinar el valor faltante en la afirmación 3
$$
\text{Afirmación 3: } m\angle8 + m\angle5 = 180^\circ \implies \text{Ángulo faltante: } 8
$$
Identificar la justificación para la afirmación 7
$$
\text{Afirmación 7: } m\angle3 + m\angle4 = m\angle8 + m\angle5 \implies \text{Razón: Substitution Property of Equality}
