As long as two adjacent interior angles have the same sum or are not supplementary, two line segments can be considered as being parallel.
How do you know if line segments are parallel or perpendicular?
Perpendicular lines are formed when two lines have the same slope and the slope of one line is equal to the slope of the other.
Which pair of segments are parallel?
Parallel lines are pairs of lines that do not meet or intersect at any point. Parallel but not intersecting lines are found on the same plane. Parallel lines or rays are those that are on the same plane but do not meet. The two lines PQ and RS are parallel to each other in the above example.
Do parallel lines have the same slope?
Parallel lines’ slopes are equal, in other words. Two lines are said to be parallel if their slopes are the same and their y-intercepts are dissimilar. To put it another way, perpendicular slopes are the opposite of each other in terms of their reciprocals.
How do you find a line parallel to a given point?
Use the point’s coordinates for (x1, y1) in point slope form to find a line that is perpendicular to a line and passes through that point (x – x1). The slope of the old line can then be used to calculate m.
