Chapter 12.2, Problem 22E

To determine

To verify: the two lines are parallel using protractor.

Explanation of Solution

Given information : Some transversals intersect two parallel lines and make two parallel lines appear to be curved.

Concept used : If a transversal line intersect two lines and the corresponding angles are equal, it can be said that two lines are parallel.

Procedure:

Here, two red colored lines are intersected by many transversals throughout the length. So, first I measure corresponding angles corresponding to each transversal line. If the corresponding angles corresponding to each transversal line are equal, it can be said that two red colored lines are parallel.
