Perpendicular is mostly used to describe Shapes and their properties. It means when two lines meet up at a 90 degrees right angle. It might be an X or a T when you look at it. Like the example shown below:

So that isn't a good drawing, but it does show you the meaning of perpendicular!

In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle
The diagonals of a square are always perpendicular.
No, not necessarily. It would have to also be a square or a kite in order to have perpendicular diagonals.
You draw a perpendicular at the end of a line segment. You then bisect the right angle formed between the original line and the perpendicular. The resulting angle will be 45 degrees.
90 degrees
Intersecting, perpendicular.
