Answer:

3) Reflexive Property

4) SAS

Step-by-step explanation:

1. The Reflexive Property states that: a quantity is congruent (equal) to itself.

Example: a = a
In this case, it could be seen as ST ≅ ST because they have/are the same side(s).

1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.

Example: RST ≅ UTS (both have S and T)
Can be seen as RST ≅ UST as well to make their similarity more evident.

2. Because it is given that RS ≅ UT and RT ≅ US, and it includes the same 2 lines being equal as given/said, RST ≅ UTS because of SAS (theorem).
