Use the drop-down menus to complete the paragraph proof showing that alternate interior angles are
congruent.
We know that lines a and b are parallel and that line e
is a transversal because that is given. We can tell that
angles 2 and 5 are congruent because
] angles are
congruent. Angles 5 and
7 are congruent because
angles by
parallel lines cut by a transversal are congruent.
Therefore, angles 2 and 7 are congruent based on the
