• if distance AX = distance BX, then m∠BAX = m∠ABX
• if m∠ABC = m∠XYZ, then m∠XYZ = m∠CBA
• if m∠ABC = 180, then ∠ABX and ∠XBC are supplementary
• if ∠ABC and ∠DEF are supplementary, then (m∠ABC) + (m∠DEF) = 180

• if a + b = c, then a = c + (b ⋅ (-1))

• if m∠ABC = 180, then ∠ABX and ∠XBC are supplementary
• if ∠ABC and ∠DEF are supplementary, then (m∠ABC) + (m∠DEF) = 180

• if the following are true:

  • a + b = c
  • a = d

  then d + b = c

• if a + b = c, then b = c + (a ⋅ (-1))

• if the following are true:

  • a = c
  • b = c

  then a = b

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