A plane intersects a line at a point, and i plane intersects another plane at a line.
Into plane
sagittal plane is a vertical plane that divides sth to left and right parts coronal plane is a vertical plane that divides sth into anterior and posterior parts
Point
It depends on where and what ABC and DEF are!
* Cartesian co-ordinate system * The complex plane is called Argand Plane
In the Argand diagram (complex plane), numbers on the horizontal axis represent real numbers.

A complex number, z, may be written as z = x + iy where x and y are real and i is the imaginary square root of -1. x is the real part of z and iy is its imaginary part. The Argand diagram for z would show it as if it had the coordinates (x, y) in the Cartesian plane. However, where the Cartesian plane has the x-axis the Argand diagram has the real part, and where the Cartesian plane has the y-axis the Argand diagram has the imaginary part. Equivalently, z can be defined in terms of polar coordinates: z = (r, q). This is the same as z = rcosq + i*rsinq, so the real part is rcosq.
The idea of graphing complex numbers was published by Argand in 1806. See related link.
