I really need help with these. If you could name the steps to start it'd be perfect. I don't want the solution but if my answers are wrong please let me know. Thank you for reading. Images are included.

11. If line PQ is congruent to line QR, find the measure of angle PTQ

My answer is 90 degrees

Options:
A. 45 degrees
B. 60 degrees
C. 90 degrees
D. not enough information given to determine

The following questions are about proving theorem 6.2. Which is: Opposite angles of a parallelogram are congruent.

12. The best reason for statements 3, 5, and 7 in this proof is
My answer is theorem 3.4.Interior angles on the same side of the transversal are supplements.

I just want to know whether it is right or wrong so I won't post the other answers, however if requested I will post them.

13. The best statement for reason 6 of this proof is
my answer: angle B and angle D are supplements.

other options:
B. Angle A is congruent to angle A
C. Angle B is congruent to angle D
D. Angle A is congruent to angle C

Thank you for viewing I really hope you will help.
