In Geometry, lines go on to infinity in both directions. This is why arrows are used. The two letters, E and F define that line. Of course if you were to measure the distance from E to F, that would be a line segment or part of the line.

It is designed to easily cut curves. Whether it cuts in straight or curved lines depends how good the user is: a good user will be able to use it to cut straight lines, but a not-so good user will tend to "wobble" and so cut lots of little curves when trying to cut in a straight line.
first we will put the divider in the starting of line then we will make points than we can measure it.
A Jigsaw would be a good power tool to cut along a curved line.
You can measure a curved line on a map by using a string or measuring tape to match the curve and then measuring the length against a ruler or a map scale. Alternatively, you can break down the curve into smaller straight line segments and then add up their lengths to get an estimate.
You can measure the length of a curved line by using a flexible measuring tape following the curve or by breaking it down into smaller straight segments and adding them up. Another option is to use a formula that calculates the arc length of a curve based on its equation and limits.
Use a thread to measure the length of curved line AB. Put a knot on the thread near one of its end. Place this knot on on point A. Now, place a small portion of thread along the line, keeping it taut using your fingers and thumbs. Hold the thread at this end point with one hand. Using other hand, stretch a little more portion of the thread along the curved line. Go on repeating this process till the other end B of the curved line is reached
A curvy line is that is used for rounded angles. This makes it easier to measure.
Use a line integral.
Yes.
A caliper or a micrometer is typically used to measure curved lines in a laboratory setting. These instruments provide precise measurements of the length or diameter of curved objects such as tubes or spherical surfaces.
Put a string over the curved line. Measure the string. If you want to do it by calculations for some known function, use integration. Divide the curved line into many small pieces, so that each piece can be approximated by a straight line, and use Pythagoras' Formula for each piece: length = square root of (width2 + height2), using the width and height of the piece. In calculus books, you'll find methods that can get you an exact result in some cases.
A graduated cylinder, measuring cup, or beaker can be used to measure liquid volume accurately. It is important to use the correct measuring tool and ensure the meniscus (the curved surface of the liquid) is at the correct measurement line for accuracy.
Depending on how deep it is and how much money you have, you would use a plumb line or sonar.
