Hope this helps <3</span>
Answer:
A is that they both are triangles and they both have right angles
Step-by-step explanation:
i dont know what B is sorry :-(
Answer:
The two column proof can be presented as follows;
Statement
Reason
1. RUST is a rectangle
Given
2. RU = ST ; UT = RS
Definition of a rectangle
3. ∠STU and ∠SRU are right angles
Definition of a rectangle
4. ΔURS ≅ ΔSTU
By SAS rule of congruency
5. ∠USR = ∠SUT
By CPCTC
Step-by-step explanation:
Given that the side RU, the angle ∠SRU and the side RS of triangle ΔURS are congruent to the side ST the angle ∠STU and the side UT of triangle ΔSTU, then ΔURS is congruent to ΔSTU, by the Side-Angle-Side (SAS) rule of congruency
Therefore, we have that ∠USR ≅ ∠SUT and therefore, it can be shown that ∠USR = ∠SUT using the Congruent Parts of Congruent Triangle are Congruent (CPCTC) postulate.
