• SSS postulate 


  Side-side-side
• SAS postulate 


  Angle between 2 sides
• ASA postulate 


  Side in between 2 angles
• AAS postulate 


  Angle-angle-side
• Triangle inequality theorem


  The sum of lengths of any two sides of a triangle is greater than the length of the remaining side.
• Transversal

  A line that crosses parallel lines to create pairs of congruent and supplementary angles
• Congruent 


  Having the same measurement
• Supplementary 


  Angles that add up to 180°
• Corresponding 


  Angles that lie on the same side of the transversal and on the same side of the parallel lines. These angles are in the same "corner" and are congruent
• Alternate interior 


  Angles on opposite sides of the transversal and inside the two parallel lines. These angles are congruent.
• Alternate exterior

  Angles on opposite sides of the transversal and outside the parallel lines. These angles are congruent
• Same-side interior

  Angles on the same side of the transversal and inside the parallel lines. These angles are supplementary.
• Same-side exterior 


  Angles on the same side of the transversal and outside the parallel lines. These angles are supplementary
• Vertical 


  Angles that are across from each other and are formed by any intersecting lines (not just parallel lines and transversals) these angles are congruent
• Hinge theorem 


  if two sides of two triangles are congruent and the included angle is different, then the angle that is larger is opposite the longer side.
