• if WXYZ is a parallelogram, then distance WX = distance ZY
• if m∠ABC = 180, then distance AC = (distance AB) + (distance BC)
• if m∠ABC = 180, then distance AC = (distance AB) + (distance BC)

• if the following are true:

  • a = b + c
  • x = y + z
  • a = x
  • b = z

  then c = y

• if ABCD is a parallelogram, then AB || DC
• if (AB || CD) and (m∠AXB = 180) and (m∠CYD = 180), then XB || CY
• if distance AB = distance CD, then distance AB = distance DC
• if (distance XY = distance ZW) and (XY || WZ), then XW || YZ
• if AB || CD, then BA || DC
