Key Elements	Green The given, the prove statement, and the appropriate amount of statments and reasons are inclued in the two-column proof. The diagram is drawn correctly.	Yellow One key element is missing.	Red More than one key element is missing.
Structure	Green The proof is written as a two column proof. The columns are labeled. All statments and reasons are numbered.	Yellow One structure element is missing.	Red More than one structure element is missing.
Flow	Green The proof uses sound reasoning based on algebraic properties, definitions, postulates, and theorems with no gaps in the reasoning.	Yellow There is one gap in the reasoning of the proof.	Red There are multiple gaps in the reasoning of the proof.
Clarity	Green The proof is written using accepted geometric/algebraic terms and notation	Yellow NOT AVAILABLE	Red The proof is not written using accepted geometric/algebraic terms and notation.
