Why does the length of the parallel decreases towards the pole?
You may be thinking of the distance between lines of longitude. The length of the lines of latitude decrease because the Earth is round, so the length of the line is shorter at the poles than it is at the Equator. The distance between the lines of longitude is shorter as you move toward the poles, again, because the Earth is round. All lines of longitude are the same length.
When a person is using an inclined plane it decreases the amount of what need to move an object?
When a person is using an inclined plane it decreases the amount of force needed to move the object.
Can a single line be parallel to itself?
Normally 2 equidistance lines are needed to designate them as parallel lines. If we say parallel lines, we mean different lines. However, we can say that the line can be parallel to itself if we move it to another dimension. For example, if the line lives in 2D, we can paralleled move it it in the 3D space, and move it again where it was, or vice versa. The beauty is that this line has a unique position on the plane, but in 3D it has infinitely many positions without breaking the condition, the same direction.
What do parallel lines mean?
It means the lines will never meet, even if they went on infinitely long. The lines move in exactly the same direction, even if their length is different. Another way to think about it, is that you could lay one line over the other, and you would only see one line (because they line up exactly).To help visualize this, lay to pencils side by side so that the eraser is flush with something (a piece of paper, table end, etc.). These pencils are said to be parallel.With a square, the "top" and "bottom" lines are parallel to each other. The "left" and "right" lines are parallel to each other. But, for example, the "top" and "left" lines are perpendicular to each other, which just means they form a 90 degree angle.The symbol used to denote parallel is: ∥ (two parallel lines actually)So A ∥ B just means A is parallel to B.
How do you find right angle of 40x100 square?
Move to a universe where a square does not have 4 sides the same length!
