Because if they did not, then they would not be number lines!

The relationship is one of identity. The number of lines of symmetry for any object, are always identically equal to the number of lines of symmetry for that same object.The relationship is one of identity.

No, a lot more.NTSC is the system used in North America for standard definition television. NTSC does not dictate the number of lines in the image but almost universally, the number of lines making the complete signal is 525. There are a number of lines that do not contribute to the image. The number of lines used for the picture is 480 with most of the remaining lines carrying other data such as closed captioning and various test lines.The other major system is PAL, used in UK, Europe and other parts of the world. PAL is generally used with 625 lines of which 576 are used to create the image.HD television uses either 720 or 1080 lines - a huge improvement over standard definition systems,No, a lot more.NTSC is the system used in North America for standard definition television.

An odd number of lines are used in interlaced scanning because, in each field of the TV, the scanning displaces the field by a half of the area. If there were an even number of lines, it would flicker noticably.
Math students.
The Mayans used a combination of dots and lines to represent their numbers. The number thirteen is represented by three dots on top of two horizontal lines.

There are generally about 720 scan lines that are used on an HD camera, but all cameras are different, so there could be more or less scan lines than provided.
Number lines are used in a variety of ways to help children learn arithmetic. They can be used to play games to get a child familiar with the numbers' sequence, shape and their relationship to each other eg. bigger, smaller etc.

All television images are made up from multiple horizontal lines. The earliest televisions used just 30 lines. Today's standard definition televisions use 480 lines in North America, Japan and other countries or 576 lines in Europe and many other countries. With the move towards HD, the number of lines has increased. The common line counts are 720 or 1080 and these are used worldwide. Another standard for HD is 1035 lines although this has fallen into disuse and is rarely seen. Super HD is an emerging standard and one that is used for certain high resolution applications and this features 2160 lines. This format is not used outside some specialist commercial applications.
