I think that if they are congruent then their measure will be 90° each.
Am I right.?

let ABCD is a //gm
then ab//cd
since , if ab//cd , co-interior angles are supplementary
angleA+angleC=180°
2angleA=180°
hence angle A=90°
therefore, angleA=angleC=90°
then ab//cd
since , if ab//cd , co-interior angles are supplementary
angleA+angleC=180°
2angleA=180°
hence angle A=90°
therefore, angleA=angleC=90°
