Two lines are parallel if they never cross one another. Another way to tell if they are parallel is if they have the same slope. Also, if the same line intersects both of them at a 90 degree angle, they would be parallel (in other words, if both lines are perpendicular to a common line, they are paraellel).

What are the proofs that a quadrilateral ia s parallelogram?
There are 5 ways to prove a Quadrilateral is a Parallelogram. -Prove both pairs of opposite sides congruent -Prove both pairs of opposite sides parallel -Prove one pair of opposite sides both congruent and parallel -Prove both pairs of opposite angles are congruent -Prove that the diagonals bisect each other
How can you determine if two lines are parallel?
There are three ways to find if two lines are parallel. The first one is to see if there is any indication. I there isn't, you should never trust your eyes. Instead, you should find the slope of each line. If they are then the two lines are parallel. Another way to find if two lines are parallel is to see if there are any corresponding angles, Alternate Interior Angles, and Alternate Exterior Angles. If there are and they are congruent, then the two lines are parallel.
What are three ways a rectangle and a square are the same?

What is the symbol for skew lines?
Well, darling, the symbol for skew lines is an "S" with a slash through it. It's like a big ol' "NOPE" sign for lines that will never meet no matter how much they try. So, if you see that symbol, just accept that those lines are going their separate ways and move on with your life.
How many parallelograms can be formed when a set of 5 parallel linesintersect 4 parallel line?
Select two parallel lines out of 5: 5*4*3/(2*1) = 30 ways Select two parallel lines out of 4: 4*3*2/(2*1) = 12 ways Combine the above 2: 30*12 = 360 parallelograms.
What are the ways to tell that lines are parallel?
U cant, its imposiible man
How do you tell if lines on a graph are parallel?
two ways : 1. calculate the slope of the two lines, if it is same, they are parallel. 2. draw a perpendicular line ( 90 degrees) from on of the lines and if it intersects the other line at 90degrees then they are parallel -HD
What are the three ways in which two lines may be related?
Parallel, Perpendicular, and Planes.
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

Does the letter G have parallel lines?
No, the letter G does not have any parallel lines, but there are a few ways of looking at it. If you assume the arc of the letter (the part that makes the shape of a C) as one line, then the letter G doesn't have any parallel lines. But... If you assume the arc as to being a lot of individual lines, and NOT an arc, then it is likely that the letter G does have a parallel line or two.
What are two ways a square and a rectangle are alike?
