The usual definition is that the lines should be straight. On "alternative geometries", other definitions may be used. For example, on a sphere, the large circles (the largest you can make, whose center is the center of the sphere) replace straight lines. Note that in this case, the normal parallel axiom is no longer valid.
What else can I help you with?
Different types of lines in mathematics?
Different types of lines are :parallel lines, intersecting lines, perpendicular lines,oblique lines, vertical lines, horizontal lines, zigzag lines, curved lines ,wavy lines, and dashed or dotted lines.
Does perpendicular have parallel lines?
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
Can parallel lines be intersecting lines?
No, parallel lines do not intersect, and never will.
What 3d shapes have a curved surface and two parallel congruent circular bases?
A cylinder has two parallel congruent faces and a curved surface.
Do parallel lines meet at a 30 dregrese angle?
Lines that meet are not parallel, and parallel lines never meet.
Does a oval have parallel lines?
No. An oval consists of curved lines.
How capacitor is denoted?
2 parallel lines. sometimes one line is curved, if so that is the outside or "shield" foil.. ANSWER : A curved parallel line define a less positive terminals of the two lines. capacitors do not have shields
How many curved lines does a oval have?
An ellipse has just one. An oval can also refer to a circle that has been stretched by inserting two parallel straight sections - as in a running track. In such cases, it has two curved lines.
Different types of lines in mathematics?
Different types of lines are :parallel lines, intersecting lines, perpendicular lines,oblique lines, vertical lines, horizontal lines, zigzag lines, curved lines ,wavy lines, and dashed or dotted lines.
Can there be parallel lines in a circle?
The two points on exactly opposite sides of a circle are parallel to each other. This can be evidenced by finding the derivative/gradient at those points; if they are the same then the two line segments described by those points are parallel.
Are latitude and longitude lines curve or straight?
Latitude lines are parallel straight lines that run east-west, while longitude lines are not parallel to each other and appear curved when projected onto a map. Longitude lines converge at the poles and are widest at the equator.
How many parallel lines in a cylinder 2?
A cylinder includes an infinite number of parallel lines. Every line in the curved surface is parallel to every other one and perpendicular to the two ends. . "A cylinder 2" is meaningless. You would have to look at the homework you're trying to get the answer for to see what cylinder 2 means.
What are the curved lines?
Lines that is curved. E.G the outline of a circle.
Are curved lines wavy lines?
Multiple curves, or arcs, comprise a wave which generally consists of a crest (high point) and a trough (low point). So generally speaking, a wavy line would be two or more curved lines that are connected.
When are two lines nonintersecting?
When two lines are parallel, then they do not intersect.
Are parallel lines actually parallel?
If they were not actually parallel then they would not be parallel lines!
Which directions does a Parallel go?
If you mean a 'parallel' of latitude on the earth, then it is a circle that proceeds east and west from any point on it. There can be any desired number of them, the only specification being that every point on the 'parallel' has the same geographic latitude. Since these are all curved lines, it's hard to say that they are parallel in the same sense as parallel straight lines on a flat surface. But the planes they lie in are all truly parallel planes.
