Angles in a transversal of parallel lines are congruent based on several reasons.
The justification for statement 2 is: alternate interior angles are congruent
From the complete question (see attachment), the statement 2 is:
[tex]\mathbf{\angle 4 \cong \angle 5}[/tex]
Base on the positions of angle 4 and angle 5,
Angle 4 and angle 5 are in alternate positions, and they are both interior angles of the transversal that passes through the parallel lines b and c.
The highlight above means that:
The angles are alternate interior angle
So, the justification for [tex]\mathbf{\angle 4 \cong \angle 5}[/tex] is: alternate interior angles are congruent
