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.

What is the distance between (−10, −2) and (−4, −2) ? −14 units −6 units 6 units 14 units
Lesechka [4]

Answer:

6 units

Step-by-step explanation:

to calculate the distance d between the points use the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁)²

with (x₁, y₁ ) = (- 10, - 2) and (x₂, y₂ ) = (- 4, - 2)

d = \sqrt{(-4+10)^2+(-2+2)^2} = \sqrt{6^2+0^2} = \sqrt{36} = 6
