Complete the two-column proof by providing a reason for each of the five statements. Given: Rectangle R U T S Prove: ∠ U S R = ∠

Fantom [35]

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.
