• (distance AB) / (distance CD) = (distance BA) / (distance DC)

• if the following are true:

  • a = b
  • b = c

  then c = a

• if (m∠ADC = 180) and (m∠BEC = 180), then m∠ACB = m∠DCE

• if a = b, then b = a

• if (m∠ABC = m∠XYZ) and ((distance AB) / (distance XY) = (distance BC) / (distance YZ)), then △ABC ∼ △XYZ
• if △ABC ∼ △DEF, then m∠BCA = m∠EFD
• if m∠CDE = m∠CAB, then DE || AB

Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
