• if ∠ABC is a right angle, then m∠ABC = 90
• if ∠ABC is a right angle, then m∠ABC = 90
• 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 90 + a = 180, then a = 90

• if m∠ABC = x, then m∠CBA = x

• if the following are true:

  • a = c
  • b = c

  then a = b

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

• if the following are true:

  • a = c
  • b = c

  then a = b

• if △ABC ≅ △DEF, then distance AC = distance DF

• if the following are true:

  • a = b
  • a = c

  then b = c

• if distance XZ = distance YZ, then m∠ZXY = m∠ZYX
• if m∠ABC = 180, then m∠XAB = m∠XAC
• if m∠ABC = 180, then m∠XCB = m∠XCA

• if the following are true:

  • a = x
  • b = y
  • x = y

  then a = b

• if (m∠ABC = m∠XYZ) and (m∠CAB = m∠ZXY) and (distance AC = distance XZ), then △BAC ≅ △YXZ
• if △ABC ≅ △DEF, then △BAC ≅ △EDF
• if (△ABC ≅ △GEF) and (△DEF ≅ △GEF), then △ABC ≅ △DEF
