Consider a plane defined by the equation. A two-dimensional Cartesian coordinate system is formed by two mutually perpendicular axes. Therefore the distance between them would be denoted by d where.
To find the distance between A 11 and B 34 we form a right angled triangle with AB as the hypotenuse.
Therefore the distance between them would be denoted by d where. The distance between the two points x 1y 1 and x 2y 2 is For example. Then the normal vector to the plane is. Therefore the distance between them would be denoted by d where.
