Question

complete the two - column proof. given: ∠dbv≅∠mpg and ∠tbd≅∠wfb prove: ∠rfp≅∠mpf
statement reason
∠dbv≅∠mpg given

  1. ∠tbd≅∠wfb 5. given
  2. (overline{tv}paralleloverline{wr}) 6. if corresponding
  3. (overline{tw}paralleloverline{mc}) 7. if alternate
  4. (overline{wr}paralleloverline{mc}) 8. transitive
  5. ∠tbd≅∠mpf 9.
  6. 10.

write the statements and reasons in the correct order in the two - column proof. ∠pfr≅∠mpf given
∠tbd≅∠wfb transitive property of congruence
∠pfr≅∠tbd if two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.
∠tbd≅∠mpf if two parallel lines are intersected by a transversal, then the corresponding angles are congruent.
(overline{tv}paralleloverline{mc}) if alternate exterior angles are congruent, then the two lines that are intersected by a transversal are parallel.
(overline{tv}paralleloverline{wr}) if corresponding angles are congruent, then the two lines that are intersected by a transversal are parallel.

Explanation:

Step1: State given angles

$\angle DBV\cong\angle MPG$ (Given) and $\angle TBD\cong\angle WFB$ (Given)

Step2: Determine parallel lines from corresponding - congruent angles

Since $\angle TBD\cong\angle WFB$, then $\overline{TV}\parallel\overline{WR}$ (If corresponding angles are congruent, then the two lines that are intersected by a transversal are parallel)

Step3: Determine another set of parallel lines from alternate - congruent angles

Since $\angle DBV\cong\angle MPG$, then $\overline{TW}\parallel\overline{MC}$ (If alternate exterior angles are congruent, then the two lines that are intersected by a transversal are parallel)

Step4: Use transitive property for parallel lines

Since $\overline{TW}\parallel\overline{MC}$ and $\overline{TV}\parallel\overline{WR}$, then $\overline{WR}\parallel\overline{MC}$ (Transitive property of parallel lines)

Step5: Find congruent angles from parallel lines

Since $\overline{WR}\parallel\overline{MC}$ and they are intersected by a transversal, $\angle TBD\cong\angle MPF$ (If two parallel lines are intersected by a transversal, then the corresponding angles are congruent)

Step6: Use transitive property of congruence

Since $\angle TBD\cong\angle WFB$ and $\angle TBD\cong\angle MPF$, and $\angle PFR\cong\angle WFB$ (Vertical angles are congruent), then $\angle PFR\cong\angle MPF$ (Transitive Property of Congruence)
