Depends.


You don&#39;t bother to mention which segment, DE, EF, or FD is the base, nor do you say which angle, D, E, or F is the vertex angle.


So you either have a vertex angle D that measures 20 degrees and two other angles that are equal in measure and the sum of all three is 180 degrees, or angle E has to be congruent to angle D.
