WebIn geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the (infinite) line perpendicular to the tangent line to the curve at the point. A normal vector may have length one (in which case it is a unit normal vector) or its length may represent the …
WebA student asks, MathHelp replies, The method is Find two vectors that are parallel to the plane. Find the normal to the these two vectors. Find the general equation of a plane perpendicular to the normal vector. Substitute one of the points (A, B, or C) to get the specific plane required.
