Evaluation Summary for Quantitative Lit.: RQLT Task 4

Final Score:

Does not Meet

Overall comments:

A two-column was provided in the submission and reflected generally appropriate mathematical logic. Some revisions are needed to ensure that the steps in the proof adequately lead to the statement being proven.

Criterion Score: 2.00 

A. Proof 

(0) Unsatisfactory

(1) Needs Revision

(2) Satisfactory

The candidate does not accurately complete the appropriate proof using a 2-column proof format with statements on the left and reasons on the right. 

The candidate accurately completes all but 1 to 2 steps of the appropriate proof using a 2-column proof format with statements on the left and reasons on the right. 

The candidate accurately completes the appropriate proof using a 2-column proof format with statements on the left and reasons on the right. 

Criterion Score: 1.00 
Comments on this criterion: The submission included a two-column proof that was on the right track to show that triangle DGF is isosceles. The use of ASA was appropriate. Revisions are needed, though, to determine if some of the steps were necessary (e.g., steps 3 through 6) as well as to make sure that the supporting reasons are adequate (e.g., steps 2, 7, 9, and 10).

B. Sources 

(0) Unsatisfactory

(1) Needs Revision
