If you have two parallel lines, then they have the same slope. If you have another line, in the same plane as the first two lines, and it is not parallel to them, then the angle of intersection with the first line will be the same as the angle of intersection with the second line. If this angle is 90°, then the third line is perpendicular to the first line and also to the second line.

For an example, think of a rectangle. Two opposite sides are parallel. Now pick one of the 3rd or 4th sides. Each of these sides is perpendicular to both the first side and the second side.

In a plane if two lines are perpendicular to the same line then they are parallel to each other?

Yes they are. It's a postulate: In a plane two lines perpendicular to the same line are parallel.


If two lines are perpendicular to the same line then the two lines are parallel?

They are parallel to each other.


Is two lines connected by their perpendicular is parallel?

Parallel lines run in the same direction. If they are intersected by one line and that line is perpendicular to both, then it proves that the lines run parallel to each other.


Line l is parallel to line m line l is perpendicular to line p what conclusions can be drawn about the relationship between lines m and p?

Lines are parallel if they are perpendicular to the same line. Since the lines m and l are parallel (given), and the line l is perpendicular to the line p (given), then the lines m and p are perpendicular (the conclusion).

Do perpendicular lines have the same exact slope?

No, parallel lines have exactly same slope Perpendicular line have a slope that is negative reciprocal of each other that is if m = slope of line then slope of perpendicular line is -1/m


Are Two lines perpendicular to a third line parallel?

Two lines that are both perpendicular to a third line are not parallel to each other unless they are the same line. In Euclidean geometry, if two lines are perpendicular to a third line, they will meet at the same angle to that line, creating a right angle. However, they can diverge from each other, resulting in them intersecting at some point rather than being parallel. Thus, they are not necessarily parallel.
