Answer:
A and D
Step-by-step explanation:
Isosceles triangles have two equal sides and angles, which are corresponding sides and angles.
Angle RTS is an isosceles triangle with RT and TS as corresponding sides, and not RS to either sides.
Angle SXT is also an isosceles triangle with XS and TX as the corresponding sides and not TS to either of both.
So, RS and RT, as well as XS and TS are not sides that are not cooresponding.
