• if (WX || YZ) and (m∠ZXR = 180), then m∠YZR = m∠WXR
• if (WX || YZ) and (m∠YWR = 180), then m∠ZYR = m∠XWR
• if m∠ABC = m∠XYZ, then m∠CBA = m∠ZYX
• if (m∠CAB = m∠ZXY) and (m∠ABC = m∠XYZ), then △ABC ∼ △XYZ
• if △ABC ∼ △DEF, then △BCA ∼ △EFD
• if △ABC ∼ △DEF, then △DEF ∼ △ABC
• if △ABC ∼ △DEF, then (distance FD) / (distance CA) = (distance EF) / (distance BC)

• if the following are true:

  • a = b / c
  • b = d

  then a = d / c

• if the following are true:

  • a = b
  • b = c

  then a = c

• if a / c = b / c, then b = a

• if a = b, then b = a

• if △ABC ∼ △DEF, then m∠ABC = m∠DEF

• if the following are true:

  • a = b
  • b = c

  then a = c

• if (distance AB = distance DE) and (m∠ABC = m∠DEF) and (distance BC = distance EF), then △ABC ≅ △DEF
• if △ABC ≅ △DEF, then △ABC ∼ △DEF
• if (△ABC ∼ △DEF) and (△DEF ∼ △XYZ), then △ABC ∼ △XYZ
