Step	Reason
Given information	Given
Something that leads to the conclusion that two of the sides or two of the angles previously unrelated are, in fact, congruent	Theorem or Postulate that proves this step.
Something that leads to the conclusion that a different pair of sides or angles previously unrelated are, in fact, congruent	Theorem or Postulate that proves this step.
Keep doing this until you have shown an SSS, SAS, ASA, or AAS relationship exists, at which point state that the triangles are congruent	correct Triangle Congruence Theorem that proves this step.
