Question

What is the difference between perpendicular and normal?

No spams please

Answer 1

Answer:

Answer:A normal is an object such as a line or vector that is perpendicular to a given object. For example, in the two-dimensional case, the normal line to a curve at a given point is the line perpendicular to the tangent line to the curve at the point. If normal is 90 degree to the surface, that means normal is used in 3D
