• if △ABC ∼ △DEF, then m∠ABC = m∠DEF
• if ray BD bisects ∠ABC, then m∠DBC = (m∠ABC) / 2
• if ray BD bisects ∠ABC, then m∠DBC = (m∠ABC) / 2

• if the following are true:

  • c = a / b
  • d = a

  then c = d / b

• if the following are true:

  • a = c
  • b = c

  then a = b

• if △ABC ∼ △DEF, then m∠BCA = m∠EFD
• if (m∠ABC = 180) and (m∠IJK = 180) and (m∠XCA = m∠YKI), then m∠XCB = m∠YKJ
• if (m∠CAB = m∠ZXY) and (m∠ABC = m∠XYZ), then △ABC ∼ △XYZ
• if △ABC ∼ △DEF, then (distance AB) / (distance DE) = (distance AC) / (distance DF)
