  1. 2. If the three sides of one triangle are congruent to the three sides of another triangle then the triangles are congruent.
  2. 3. Two equal sides two equal base angles.
  3. 7. A quantity may be substituted for its equal. If DE+CD=CE and CD=AB then DE+AB=CE.
  4. 9. A quantity is equal to itself. AB=AB
  5. 11. This states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent
  6. 12. if two pairs of corresponding angles and also if the included sides are congruent, then the triangles are congruent.

  1. 1. A whole is equal to the sum of its parts. If point C is on AB then AC+CB=AB.
  2. 4. The sum of the two opposite interior angle of a triangle are equal to the.
  3. 5. A squared plus B squared equals C squared.
  4. 6. if two angles of a triangle are respectively equal to the two angles of another triangle, we can prove that the third will also be equal on both triangles.
  5. 8. If two quantities are equal to the same quantity then they are equal to each other. If AB=BC and BC=EF then AB=EF.
  6. 10. All three angles are congruent and are equal to 60 degrees.
