  1. Line Intersection Theorem:
    two different lines intersect in at most one point.
  2. Betweenness Theorem:
    If B is between A nad C, then AB + BC = AC
  3. Theorem (unnamed):
    For any three points A, B, and C, AB + BC > AC.
  4. Linear Pair Theorem:
    Vertical Angle Theorem:
    • If two angles form a linar pair, then they are supplementary.
    • If two angles are vertical angles, then they have equal measures.
  5. Perpendicular Lines and Slopes Theorem:
    Two non-vertical lines are perpendicular if and only if the product of their slopes = -1.
  6. Parallel Lines and Slopes Theorem:
    Two non-vertical lines are parallel if and only if they have the same slope.
