If cos θ - sin θ = √2 sin θ, then prove that cos θ + sin θ = √2 cos θ.
belka [17]

Step-by-step explanation:

cos θ - sin θ = √2 sin θ

cos θ + sin θ = √2 sin θ + 2sin θ

cos θ + sin θ = √2(sin θ + √2sin θ)

cos θ + sin θ = √2 cos θ. (Proven)

Can you help me write proofs for these, PLEASE!!!
brilliants [131]

Exterior angle theorem and properties of the isosceles triangles are used

prove the specified relations.

Correct responses:

9. ΔPAT ~ ΔPTB by AA similarity postulate

15. \overleftrightarrow{HM}║\overleftrightarrow{JK} by basic proportionality theorem

<h3>Detailed methods used to prove response</h3>

9. A two column proof is presented as follows;

Statement {}                                     Reasons

1. ∠PTA = ∠B {}                           1.  Given

2. ∠PAT = ∠ATB + ∠B  {}           2.  Exterior angle of a triangle theorem

3. ∠BTP = ∠ATB + ∠PTA {}        3   Angle addition postulate

4. ∠BTP = ∠ATP + ∠B {}             4.  Substitution property of equality

5. ∠PAT = ∠BTP {}                      5.  Substitution property

6. ΔPAT ~ ΔPTB {}                      6. AA similarity postulate

The Angle-Angle, AA, similarity postulate states that two triangles are similar if two angles in one triangle are each equal to two angles in the other triangle.

15. A two column proof is presented as follows;

Statement                        {}                         Reasons

\displaystyle 1. \hspace{0.3 cm} \frac{GJ}{HK}  = \frac{GK}{GM}                            {}          1.  Given

2. ∠1 ≅ ∠G                          {}                   2. Given

3. ΔKHG is an isosceles triangle{}         3. Definition

4. HK = HG {}                                            4. Legs of an isosceles triangle

\displaystyle 5. \hspace{0.3 cm} \frac{GJ}{HG} = \frac{GK}{GM}              {}                         5. Substitution property

6. \overleftrightarrow {HM} ║ \overleftrightarrow{JK}                      {}                    6. BPT, Basic Proportionality Theorem

Basic Proportionality Theorem, BPT, states that if a line parallel to one of the sides of a triangle, intersects the other two sides, then the line divides the other two sides in the same proportion.
