Answer:
just read lol i tried but i think i know everything except why line r and s are parallel
Step-by-step explanation:
∠13 ≅ ∠15 because vertical angles are congruent
∠5 ≅ ∠13 because they corresponding angles are congruent
this is a guess but i think line r and s are parallel because the alternate exterior angles are congruent if you get it wrong idk
the last one only half of it is wrong so take away the r || s
