If you measure the angle between them and it's exactly 90 degrees, then they're perpendicular.
That's the definition and the requirement.
Perpendicular lines form a "corner", but if you want to be technical about it, that's not
a good way to tell. The angle might be only 87 degrees, or it might be 92 degrees, and
when you look at it, it may look like a corner. But technically, if it's not 90 degrees then
they're not perpendicular.

What is Perpendicular and Parallel?
Perpendicular is when two lines cross... Parallel is when two lines never meet.... _____________ _____________ = PARALLEL LINES If they cross they are perpendicular, if they don't, they are parallel.
What type of angle is formed by perpendicular lines?
Right angles are formed by perpendicular lines. If the lines would extend, to make two intersecting lines, they would form four right angles. Perpendicular lines are written like this: . From its shape, you can already tell that it forms at least two right angles.
What is the difference between perpendicular and intersecting lines?
perpendicular crosses at a right angle, while intersecting lines don't
When two lines cross to form a square corner lines are called?
Mutually perpendicular.
Two lines are perpendicular if they are parallel and cross?
Parallel lines are never perpendicular. Perpendicular lines are co-planar and cross at right angles.
