How many parallelograms are formed when a set of 5 parallel lines intersect a set of 4 parallel lines?

This one is much more straightforward. There are 5C2 = 10 ways to choose two parallel lines from the set of five. There are 4C2 = 6 ways to choose two parallelograms from a set of four. Any parallelogram is uniquely determined by one pair of lines from the five, and one pair of lines from the four. Thus, the number of possible parallelograms is
(5C2)*(4C2) = (10)*(6) = 60

Two lines in the same plane that do not intersect?
They are parallel lines
What are lines that are in the same plane and do not intersect?
Parallel lines
What are two non parallel lines that do not intersect?
Skew lines
What is parallel line segment?
lines which lie in same pane are known as parallel lines or lines which do not intersect are known as parallel lines they extend in both the direction
Do perpendicular lines always sometimes or never intersect?
Perpendicular lines always intersect and make 90 degree angles. Parallel lines never intersect with each other.
What angles are formed on the inside of parallel lines?
No angles are formed on the inside of parallel lines because they do not intersect. That is the definition of parallel.
What is the term for lines that don't intersect?
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
Can parallel lines intersect?
No, never. Parallel lines are line that will NEVER intersect.
What parallel lines intersect?
Parallel lines in the Euclidean plane do not intersect but all parallel lines in the projective plane intersect at the point at infinity.
Can a parallel lines intersect?
No they cannot.If they were to intersect they wouldn't be known as parallel lines.
Are lines that never intersect parallel or perpendicular?
parallel ============================================= Parallel. _____________________ _____________________ Those two lines will NEVER intersect.
How many times do parallel lines intersect?
parallel lines never intersect.
Are two lines that are not parallel coplanar and do not intersect?
are two lines that are not parallel, coplanar, and do not intersect
Why do artists use parallel lines that do intersect?
I do not think lines can intersect if they are truly parallel.
What line intersect through parallel lines?
No line can intersect parallel lines. Parallel lines by definition never intersect.
Can parallel lines also be perpindicular?
No. Parallel lines do not intersect; perpendicular lines intersect at 90 degrees
Can two lines be parallel and have the same Y intersect?
Parallel lines are lines that never intersect. So the answer is no.
