Answer 3

Thanks just need to reword it so I understand it better.

Answer 4

Since line PQ is given to be parallel to line RS and since 4 and 8 are alternate interior angles, we know that angle 4 is congruent to angle 8 because if parallel lines are cut by a transversal, then the alternate interior angles are congruent.


Is this right?

Answer 5

yup :)

K thanks man.
