geometry - unit 2 - practice test
due sep 25 - 9:00 am
which pairs of lines are parallel?
a. r and s
b. r and t
c. s and u
d. t and u

Explanation:

Step1: Recall parallel - line angle rules

Parallel lines have equal corresponding, alternate - interior, or alternate - exterior angles.

Step2: Analyze angles formed by lines

For lines \(s\) and \(u\), the angles formed are \(87^{\circ}\) which are corresponding angles. Since corresponding angles are equal when lines are parallel, lines \(s\) and \(u\) are parallel.

Answer:

C. s and u
