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: +
Two lines which are perpendicular to each other will form four right angles and they look like a large + sign
Perpendicular is when two lines cross and form a right angle, which I hope you know what that is.
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
the at sign looks like this: @
