Question

geometry part 1ae teacher (acc ed) / angles and lines

1. why are the lines in this picture parallel?

p
l
they are equal width apart, travel in the same direction, and never meet.
they both lie in the same plane.
they both travel on forever and ever.
they are both the same size.

Explanation:

Parallel lines in a plane are defined as lines that are always the same distance apart (equidistant), have the same direction, and never intersect. Just lying in the same plane is not enough to define parallelism. Continuing forever is a property of all lines, and lines don't have a "size".

Answer:

They are equal width apart, travel in the same direction, and never meet.
