• ((m∠YWX) + (m∠WXY)) + (m∠XYW) = 180
• if ABCD is a rhombus, then distance AB = distance BC
• if distance AB = distance CD, then distance AB = distance DC
• if distance XZ = distance YZ, then m∠ZXY = m∠ZYX
• if m∠ABC = m∠XYZ, then m∠CBA = m∠XYZ

• if the following are true:

  • a + b = c
  • b = d

  then a + d = c

• if (a + b) + b = 180, then a + (b ⋅ 2) = 180

• if the following are true:

  • a + b = c
  • a = d

  then d + b = c

• if 60 + (a ⋅ 2) = 180, then a = 60

• if the following are true:

  • a = c
  • b = c

  then a = b

• if a = b, then b = a

• if (m∠ABC = m∠BCA) and (m∠BCA = m∠CAB), then △ABC is an equilateral triangle
• if WXYZ is a rhombus, then distance ZW = distance WX
• if WXYZ is a rhombus, then distance YZ = distance ZW
• if △ABC is an equilateral triangle, then distance CA = distance AB

• if the following are true:

  • a = c
  • b = c

  then a = b

• if distance AB = distance CD, then distance AB = distance DC
• if (distance AB = distance BC) and (distance BC = distance CA), then △ABC is an equilateral triangle
