Question

parallel lines r and s are cut by two transversals, parallel lines t and u.
which angles are alternate exterior angles with angle 11?

Explanation:

Alternate exterior angles lie outside the two parallel lines, on opposite sides of the transversal, and are non-adjacent. For angle 11 (on line \(s\), transversal \(u\)), we look for an angle outside lines \(r\) and \(s\), on the opposite side of transversal \(u\) relative to angle 11. Angle 2 fits this definition: it is outside \(r\) and \(s\), on the opposite side of transversal \(u\) from angle 11, and formed by the parallel transversals \(t\) and \(u\) cutting parallel lines \(r\) and \(s\).

Answer:

Angle 2
