• a + a = a ⋅ 2
• if M is the midpoint of line AB, then distance AM = distance MB
• if M is the midpoint of line AB, then m∠AMB = 180
• if m∠ABC = 180, then (distance AB) + (distance BC) = distance AC

• if the following are true:

  • a + b = c
  • d = b

  then a + d = c

• if a + a = b, then a ⋅ 2 = b

• if a ⋅ 2 = b, then a = b ⋅ (1 / 2)

• if the following are true:

  • a = b ⋅ c
  • b = d

  then a = d ⋅ c

• if M is the midpoint of line AB, then distance AM = distance MB
• if M is the midpoint of line AB, then m∠AMB = 180
• if m∠ABC = 180, then (distance AB) + (distance BC) = distance AC

• if the following are true:

  • a + b = c
  • d = b

  then a + d = c

• if the following are true:

  • a = b
  • a = c

  then b = c

• if a ⋅ 2 = b, then a = b ⋅ (1 / 2)

• if the following are true:

  • a = c
  • b = c

  then a = b

• if a = b, then b = a

• if m∠ABC = x, then m∠CBA = x
• if m∠ABC = x, then m∠CBA = x
• if (m∠BDA = 180) and (m∠CEA = 180), then m∠BAE = m∠CAD
• if distance AB = x, then distance BA = x
• if distance AB = distance CD, then distance AB = distance DC
• 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
