Question

Line Segment AB has a slope of 1/3 and line segment CD has a slope of 1/3. This proves that

1. Line segment AB is congruent to line segment CD
2. Line segment AB bisects line segment CD
3. Line segment AB is parallel to line segment CD
4. Line segment AB is perpendicular to line segment CD

Answer 1

3

Explanation:

Parallel lines have equal slopes, thus

line AB is parallel to line CD
