Carmen found m∠1 this way:

Measure of angle 1 = 105 degrees because if two lines are parallel, alternate exterior angles are equal.

Is her answer correct? Explain why or why not.
Parallel lines r and s are crossed by transversal t to form 8 angles. Clockwise from top left, the angles formed with line r are blank, 1, blank, blank; with line s are blank, blank, 105 degrees, 3.

Sample response: She is not correct because ∠1 is an alternate exterior angle with ∠3, not the angle that measures 105°. So m∠1 = 75°.
