  1. Side-Side-Side (SSS) Congruence Postulate All Three sides in one triangle are congruent to all three sides in the other triangle

  2. Side-Angle-Side (SAS) Congruence Postulate Two sides and the INCLUDED angle (the angle is in between the 2 marked sides)

  3. 2 markings you can add if they aren’t marked already

  4. Share a side Reason: reflexive property Vertical Angles Reason: Vertical Angles are congruent
