• (a ⋅ 2) / (b ⋅ 2) = a / b
• if △ABC ∼ △DEF, then m∠BCA = m∠EFD
• if △ABC ∼ △DEF, then (distance CA) / (distance FD) = (distance BC) / (distance EF)
• if M is the midpoint of line AB, then (distance BM) ⋅ 2 = distance BA
• if M is the midpoint of line AB, then (distance BM) ⋅ 2 = distance BA

• if the following are true:

  • a = x
  • b = y

  then a / b = x / y

• if the following are true:

  • a = b
  • a = c

  then b = c

• if the following are true:

  • a = b
  • b = c

  then a = c

• if a = b, then b = a

• if M is the midpoint of line AB, then m∠AMB = 180
• if M is the midpoint of line AB, then m∠AMB = 180
• if (m∠ABC = 180) and (m∠IJK = 180) and (m∠XCA = m∠YKI), then m∠XCB = m∠YKJ
• if (m∠ABC = m∠XYZ) and ((distance AB) / (distance XY) = (distance BC) / (distance YZ)), then △ABC ∼ △XYZ
• if △ABC ∼ △DEF, then (distance AC) / (distance DF) = (distance AB) / (distance DE)
