at the top its cut off but it askes to use the given info to complete the proof of the following theorm if you could give me the answer without explanation because im on a tight schedule i would love to leave a good reveiw thanks!

Steps:
2) QR || TS
3) QT || RS
4) <1 = <4, as they are alternate interior angles between parallels.
5) <2 = <3, as they are alternate interior angles between parallels.
6) RT = RT, by the reflexive property.
7) Triangle QRT = Triangle SRT, by the ASA postulate.
8) QR = ST and QT = RS, as they are corresponding sides of congruent triangles.
