• if AB || CD, then CD || AB
• if (WX || YZ) and (m∠WYR = 180), then m∠ZYR = m∠XWY
• if m∠ABC = 180, then m∠XAB = m∠XAC

• if the following are true:

  • a = b
  • b = c

  then a = c

• if a = b, then b = a

• if (m∠ADC = 180) and (m∠BEC = 180), then m∠ACB = m∠DCE
• if (m∠CAB = m∠ZXY) and (m∠ABC = m∠XYZ), then △ABC ∼ △XYZ
• if △ABC ∼ △DEF, then △ACB ∼ △DFE
• if △ABC ∼ △DEF, then (distance ED) / (distance BA) = (distance DF) / (distance AC)
• if distance AB = distance CD, then distance DC = distance BA

• if a = b, then b = a

• if the following are true:

  • a / b = c
  • d = a

  then d / b = c

• if the following are true:

  • a = b
  • b = c

  then a = c

• if the following are true:

  • a = b
  • b = c

  then c = a

• if a / c = b / c, then a = b

• if a = b, then b = a

• if △ABC ∼ △DEF, then (distance DF) / (distance AC) = (distance FE) / (distance CB)

• if the following are true:

  • a = b
  • b = c

  then a = c

• if the following are true:

  • a = b
  • a = c

  then b = c

• if a / c = b / c, then b = a

• if (distance AB = distance DE) and (distance BC = distance EF) and (distance CA = distance FD), then △ABC ≅ △DEF
• if △ABC ≅ △DEF, then △ABC ∼ △DEF
