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.

3.The legs of a right triangle are equal. Given the length of the legs, find the length of the hypotenuse. Round
Zepler [3.9K]

Answer:

1.41a

Step-by-step explanation:

Let ABC is a right triangle with equal legs AB =BC.  

Hence, ∠B is 90° and CA is the hypotenuse.

Now, applying Pythagoras Theorem, we can write  

CA² = AB² + BC²

Let us assume that each legs AB = BC = a.

Therefore, CA² = a² +a² = 2a²

⇒Hypotenuse or CA = a√2 = 1.41a { Round to the nearest tenth} (Answer)

Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cube
kvasek [131]

Answer:

C

Step-by-step explanation:

Tomas learned that

a^3+b^3=(a+b)(a^2-ab+b^2)

If a=2x,\ b=y, then

a^3+b^3\\ \\=(2x)^3+y^3\\ \\=((2x)+y)((2x)^2-(2x)y+y^2)\\ \\=(2x+y)(4x^2-2xy+y^2)
