Question

complete the two - column proof. given: ∠dbv≅∠mpg and ∠tbd≅∠wfb. prove: ∠rfp≅∠mpf. 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. (overleftrightarrow{tv}paralleloverleftrightarrow{mc}) if alternate exterior angles are congruent, then the two lines that are intersected by a transversal are parallel. (overleftrightarrow{tv}paralleloverleftrightarrow{wr}) if corresponding angles are congruent, then the two lines that are intersected by a transversal are parallel.

Explanation:

Step1: Identify given angles

We know $\angle DBV\cong\angle MPG$ and $\angle TBD\cong\angle WFB$ are given.

Step2: Use corresponding - angle property

Since $\angle TBD\cong\angle WFB$, by the corresponding - angle property of parallel lines (if corresponding angles are congruent, then the two lines that are intersected by a transversal are parallel), we have $\overline{TV}\parallel\overline{WR}$.

Step3: Use alternate - exterior angle property

Because $\angle DBV\cong\angle MPG$, by the alternate - exterior angle property (if alternate exterior angles are congruent, then the two lines that are intersected by a transversal are parallel), we get $\overline{TV}\parallel\overline{MC}$.

Step4: Use transitive property of parallel lines

Since $\overline{TV}\parallel\overline{WR}$ and $\overline{TV}\parallel\overline{MC}$, then $\overline{WR}\parallel\overline{MC}$.

Step5: Use corresponding - angle property again

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

Step6: Use alternate - exterior angle property again

If $\overline{TV}\parallel\overline{WR}$, then $\angle PFR\cong\angle TBD$ (if two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent).

Step7: Use transitive property of congruence

Since $\angle PFR\cong\angle TBD$ and $\angle TBD\cong\angle MPF$, by the transitive property of congruence, $\angle PFR\cong\angle MPF$.
