Notice you have 3 horizontal lines that are marked as parallel.

i see
OpenStudy (mathstudent55):
Then you have two kines running up and down.
The parallel lines cut off segments int eh two lines running up and down.

OpenStudy (mathstudent55):
The segments are marked above 1, 2, 3, and 4.

Here is a theorem:
"Three or more parallel lines cut any two transversals into proportional segments."

so would it be something like this: 1/2 = 3/4? or would it be 1=3 and 2=4?
OpenStudy (mathstudent55):
Since the horizontal lines are parallel, they cut off proportional segments in the lines running up and down.
That means
\(\dfrac{1}{2} = \dfrac{3}{4} \)
where 1, 2, 3, and 4 are the given lengths of the segments in your figure.
