sorry had to be on the phone. sum of angles in a quadrilateral = 360 degrees. did the article from the other response help? I did not read it

OpenStudy (sdfgsdfgs):

"...The base angles of an isosceles trapezoid are equal in measure (there are in fact two pairs of equal base angles, where one base angle is the supplementary angle of a base angle at the other base)." - from wikipedia

OpenStudy (triciaal):

so G = D = 121
