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
They are parallel lines
Parallel lines
Skew lines
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
Perpendicular lines always intersect and make 90 degree angles. Parallel lines never intersect with each other.
No angles are formed on the inside of parallel lines because they do not intersect. That is the definition of parallel.
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
No, never. Parallel lines are line that will NEVER intersect.
Parallel lines in the Euclidean plane do not intersect but all parallel lines in the projective plane intersect at the point at infinity.
No they cannot.If they were to intersect they wouldn't be known as parallel lines.
parallel ============================================= Parallel. _____________________ _____________________ Those two lines will NEVER intersect.
parallel lines never intersect.
are two lines that are not parallel, coplanar, and do not intersect
I do not think lines can intersect if they are truly parallel.
No line can intersect parallel lines. Parallel lines by definition never intersect.
Parallel lines are lines that never intersect. So the answer is no.
No. Parallel lines do not intersect; perpendicular lines intersect at 90 degrees
