Question 637224
<font face="Times New Roman" size="+2">


It would help if you would describe the relationship between points D, E, and F to the rest of the diagram.


Also lines cannot be congruent.  Line <b><i>segments</i></b> can be congruent.


B and C are not rays.  B and C are points.  AB and AC could be rays starting at A and going through B or C.


I really recommend you go back to the very beginning of your Geometry book so that you can properly learn the vocabulary.  Otherwise, you are never going to be able to effectively communicate what you mean when you ask for help.
