A perpendicular bisector has a right angle or 90 degrees
Nothing. A perpendicular is an adjective, not a noun. A perpendicular, by itself, cannot exist. A perpendicular bisector, for example, does not have any sides.
Two perpendicular lines must cross at a 90 degree angle, like a plus sign: +
Perpendicular is when two lines cross and form a right angle, which I hope you know what that is.
Two lines which are perpendicular to each other will form four right angles and they look like a large + sign
the at sign looks like this: @
As far as we know, two lines can be perpendicular, or they can be parallel, but they can't be both.
it would look weird because that is not possible
