• if ABCD is a parallelogram, then AB || DC
• if WS || TZ, then m∠WST = m∠STZ
• if m∠ABC = m∠XYZ, then m∠ABC = m∠ZYX
• if m∠CBA = 180, then m∠XAC = m∠XAB
• if m∠ABC = 180, then m∠XAC = m∠XAB

• if the following are true:

  • a = b
  • b = d
  • a = c

  then d = c

• if WX || YZ, then m∠YZW = m∠ZWX
• if m∠CBA = 180, then m∠XAC = m∠XAB
• if m∠ABC = 180, then m∠CAX = m∠BAX

• if the following are true:

  • a = b
  • a = c
  • b = d

  then c = d

• if m∠ABC = m∠XYZ, then m∠CBA = m∠XYZ
• if WXYZ is a parallelogram, then distance WX = distance ZY
• if distance AB = distance CD, then distance DC = distance AB
• if (m∠ABC = m∠DEF) and (distance BC = distance EF) and (m∠BCA = m∠EFD), then △ABC ≅ △DEF
