A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
The shortest distance between 2 parallel lines is a perpendicular drawn between 2 parallel lines the diagram shows it clearly 1 parallel line ------------------------------------|-------------------------------------------------------------------- | | | the vertical line is the shortest distance | | ------------------------------------|------------------------------------------------------------------- 2nd parallel line
I always remembered parallel line because of the 2 "L's" in parallel. They are perfectly parallel to each other and will never intersect. The slope of a line is the rise over run, or rise/run. Therefore if both lines are parallel, the slopes of the lines are the same.
In a 2 dimensional plain they would have to be parallel in order to have no common point; in a 3 dimensional field they do not have to be parallel.
parallel. Perpendicular mean 2 lines connect at a 90 degree angle
2 pairs of parallel lines
There are 2 sets of parallel lines.
2 parallel lines are lines that will never intersect
yes it has 2 parallel lines
A trapezoid has two parallel lines.
A rectangle has 2 "SETS" of parallel lines. SO it has 4 parallel lines.Two pairs.
A trapezoid does not has 2 pairs of parallel lines. A parallelogram does.
A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
In 2D geometry, that is the definition of parallel lines. Two non-intersecting lines are indeed parallel.
2 parralel lines are lines that are parallel to each other so they are oppoosite to eathother x
A square has 2 pairs of opposite parallel lines.
