Yes. It has 2 sets of congruent sides

No. The diagonals are not congruent.

Yes. The diagonals are congruent.

No. The two pair of congruent sides are not opposite of each other. Adjacent congruent sides do not create parallelograms.

Yes. Angle Q and R are congruent and angle S and P are congruent.

No. The angles are not congruent.

Yes. Angle Q and S are = to 140 degrees and angle P and R are = to 40 degrees.

No.Angle Q and S are not congruent. Angle P and R are not congruent.

Yes. AB is congruent to CD. BC is congruent to AD.

No. AB is congruent to CD but BC is NOT congruent to AD.

Yes. AB & CD are 17 and BC & AD are 6.

No. Not enough information.

Yes. Angle D = 153 degrees.

Yes. Angle D = 27 degrees.

No. The interior angle sum does not equal 360 degrees.

No. The adjacent angle sets are not both 180 degrees.

Yes. All adjacent angles are supplementary.
