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.
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.

That refers to lines that meet at right angles - angles of 90 degrees.

The mean is usually the arithmetic mean - there are other means in maths. For a set of numbers, the arithmetic mean is the sum of the numbers divided by the number of numbers.
it mean have to divide it i think
