In the figure, lines $a$ and $b$ are parallel and are cut by a transversal. Which pair is an alternate interior angle pair? 
A$\angle y$ and $\angle q$
B$\angle z$ and $\angle p$
C$\angle x$ and $\angle r$
D$\angle y$ and $\angle s$
Answer & Solution
Correct answer: B. $\angle z$ and $\angle p$
Alternate interior angles lie between the two parallel lines and on opposite sides of the transversal. In the figure, $\angle z$ and $\angle p$ form such a pair. Option A is a pair of corresponding angles, and D is alternate exterior.
