It just means at right angles (90°) to.
The red line is perpendicular to the blue line in both these cases:
(The little box drawn in the corner, means "at right angles", so we didn't really need to also show that it was 90°, but we just wanted to!)
Try for yourself (move points "A", "B" or "N"):
ParallelLines are parallel if they are always the same distance apart (called "equidistant"), and will never meet. (They also point in the same direction). Just remember: Always the same distance apart and never touching.The red line is parallel to the blue line in both these cases:Example 1
Example 2
Try it yourself:
Perpendicular to ParallelQuestion: What is the difference between perpendicular and parallel?Answer: 90 degrees (a right angle)
That's right, if you rotate a perpendicular line by 90° it will become parallel (but not if it touches!), and the other way around.
Perpendicular ...
Rotate One Line 90°
... Parallel !
Parallel CurvesCurves can also be parallel when they are always the same distance apart (called "equidistant"), and never meet. Just like railroad tracks.The red curve is parallel to the blue curve in both these cases:
Parallel SurfacesSurfaces can also be parallel, so long as the rule still holds: always the same distance apart and never touching.Lines and PlanesAdvanced Topic: You can also learn about Parallel and Perpendicular Lines and Planes Mind BenderSomething that makes my mind bend: we know that if we have two parallel lines, and we rotate one by 90°, they will be perpendicular to each other, right? Well, does the same apply to curves? Can you have "perpendicular curves", by rotating one of them by 90°? I simply don't know, but it is fun to think about.Parallel Lines and Pairs of AnglesParallel and Perpendicular Lines and PlanesFinding Parallel and Perpendicular Lines Using AlgebraGeometry Index
What else can I help you with?
Pendicular lines can be parallel?
No, pendicular or can say it perpendicular lines can never be parallel as the angle b/w pendiular lines is 90 and parallel is 0 or 180 and both can not be same so ......pendicular lines cant become parallel.
What is does pendicular mean in maths?
Perpendicular, or "normal", means that two lines meet at right angles. The two lines cross in such a way that they form 4 equal angles between them.If you work with coordinates, the product of the slopes of two perpendicular lines are minus 1. For example, if a certain line has a slope of 2, another line, perpendicular to it, will have a slope of -1/2.
How do you find the middle point of a circular flat object?
draw a square within the circle then draw a straight line between the two sets of opposite corners and where those lines cross is where the center of the circle is. pick ne 3 points on the perimenter of the circle..... join the 1st point to the 2nd wit a straight line & the 2nd point to the 3rd.... bisect these 2 lines with a compass or simply find the midpoint of the lines.... if u hav bisected the lines draw a strange line thru the 2 points where the arcs cross and where the 2 lines meet is the centre point.... if u got the midpoints of the 2 lines just draw a pendicular line from the midpoint of both lines & again the centre is where the 2 lines meet.... (both methods are the same realie only 4 the fact that bisecting is more accurate!!!)
