Non-parallel lines intersect at some point, parallel lines don't.
A secant line touches a circle at two points. On the other hand a tangent line meets a circle at one point.
Parallel lines are two 1-dimensional objects that do not meet. Parallel planes are two 2-dimensional objects that do not meet.
Parallel lines never intersect and remain equal distance from each other but perpendicular lines intersect at right angles
Parallel lines remain the same distance apart and never intersect each other whereas other types of lines intersect each other at some point.
The transversal is the line that cuts the parallel line.
Non-parallel lines intersect at some point, parallel lines don't.
A secant line touches a circle at two points. On the other hand a tangent line meets a circle at one point.
The difference between intersecting and parallel lines is that, on a graph parallel lines do ont touch,cross or anything. THEY NEVER TOUCH. intersecting lines touch, or cross eachother.\
Parallelogram: 2 pairs of parallel lines Trapezoid: 1 pair of parallel lines
Two lines tangent to a circle at the endpoints of its diameter are parallel. See related link for proof.
Parallel lines are two 1-dimensional objects that do not meet. Parallel planes are two 2-dimensional objects that do not meet.
The difference is in the location of their intercept with any other non-parallel line.
Parallel lines never intersect and remain equal distance from each other but perpendicular lines intersect at right angles
Parallel lines remain the same distance apart and never intersect each other whereas other types of lines intersect each other at some point.
A trapezium has one a pair of parallel lines, a parallelogram has two.
If the distance between the lines is constant then they are parallel.
