Answer:

  • Option A

=============================

The missing statement is:

  • ∠1 + ∠2 = 180°
  • ∠2 + ∠3 = 180°

Justification is:

  • Angles that form a linear pair have measures that sum to 180°.

All the other options have mismatching or wrong statements or justifications:

  • B) Wrong statement, the angles are not congruent.
  • C) Wrong justification, angles are not vertical.
  • D) Wrong justification, not matching the statement.
