Exercise 24 Page 384

The intersection of two non-parallel planes is always a line.

Example Solution:

Practice makes perfect

Let's start by drawing an arbitrary plane C.

The intersection of two non-parallel planes is always a line. Therefore, we will draw another plane, D, that is not parallel with and intersects C.


Lastly, we will draw a line where the two planes intersect. Note here that the line is to be named XY. Thus, we have to place the two points X and Y on the line as well.
