Given: ∠6≅∠7

Prove: ∠5≅∠8

Step-by-step explanation:

angle 6 ang angle 7 congruent (equal to ) because they are alternate interior angles and alternate interior angles are always equal.

angle 6 and angle 5 are congruent(equal to )  because they are vertically opposite angles and vertically opposite angles are always equal.

angle 7 and angle 8 are congrunt (equal ) because they are veritically opposite angles angd vertically opposite angles are always equal.

angle 5 and angle 8 are congruent(equal ) because they are alternate exterior angles and alternate exterior angles are also always equal.
