in 2 and 3 dimensions they turn out to be pretty much the same, but what would perpendicular mean in 4 or 6 dimensions? For example a line perpendicular to another intersects it and creates a 90 degree angle, it is also normal and a line can be normal to a plane also. Normal is a more general term that can be used in higher dimensions and other setting where perpendicular might make no sense. For example, if you know what a dot product is that two vectors are normal if their dot product is zero, These may be n dimensional vectors and perpendicular would make no sense. In many more abstract settings normal works but perpendicular would have no meaning at all.
There are more technical explanations but I hope to make this answer more intuitive!
There is a very slight difference between NORMAL and PERPENDICULAR. Well NORMAL is that perpendicular which is drawn at the contact point between two meeting lines. Its simple as this. For example in case of tangents (which is drawn to find the direction of a point in a curve) the perpendicular draw at the meeting point of the tangent and the curve is called normal. Its like, every normal is a perpendicular but all perpendiculars are not normal. I hope this clears all your doubt.

What is the difference between parallel and perpendicular line on rectangle?
The difference between a perpendicular line and a parallel line is that a perpendicular line crosses or joins, while a parallel line doesn't touch at all.
What is the difference between a perpendicular line and a perpendicular bisector?
A perpendicular line is one that is at right angle to another - usually to a horizontal line. A perpendicular bisector is a line which is perpendicular to the line segment joining two identified points and which divides that segment in two.
What is the difference between perpendicular and intersecting lines?
perpendicular crosses at a right angle, while intersecting lines don't
What is the line perpendicular to a mirror's surface?
The normal (ray).
What is the difference between oblique offset and perpendicular offset?
The measurements are taken at right angle to the survey line called perpendicular or right angled offsets. The measurements which are not made at right angles to the survey line are called oblique offsets or tie line offsets.
What is the difference between force of gravity and normal force?
"Normal" means perpendicular to something. In many practical problems, this may refer to the component of a force that is perpendicular, for example, to an inclined plane over which an object can move.
What is the difference between parallel and perpendicular line on rectangle?
The difference between a perpendicular line and a parallel line is that a perpendicular line crosses or joins, while a parallel line doesn't touch at all.
Why is it important to know the difference between parallel vs perpendicular?
perpendicular cross parallel do not
What is the difference between the force of gravity and normal force?
The force of gravity is the attraction between two masses, such as the Earth and an object on its surface, pulling them towards each other. Normal force is the force exerted by a surface to support an object resting on it, acting perpendicular to the surface. Gravity always acts downwards, while the normal force acts perpendicular to the surface.
What is the agular difference between 2 perpendicular lines?
Exactly 90 degrees, that is the definition of perpendicular.
The angle of incidence is the angle between the incident ray and the?
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
What is the difference between a right angle and a perpendicular line?
Two perpendicular lines make up a right angle
What are the difference between perpendicular lines and a perpendicular bisector?
A perpendicular bisector goes through the median of the line while a perpendicular line can be anywhere on the line as long as it is at a 90 degree angle.
What is the angle of incidence to the normal incidence?
The angle of incidence is the angle between the incident ray and the normal (perpendicular line) to the surface. In normal incidence, the incident ray is perpendicular to the surface, so the angle of incidence is 0 degrees.
What is the different of a perpendicular lines and intersecting lines?
The only difference between perpendicular lines and intersecting lines is that perpendicular lines create a right angle at the point of intersection.
what difference between perpendicular/base and 1/2 * base *height?
2
What is the difference between perpendicular lines and perpendicular line segments?
Lines have no end (stretch on forever) Line segments start and end.
