Exercise 21 Page 384

For plane M and NB to intersect at point B, B has to lie in plane M.

Example Solution:

Practice makes perfect

For plane M and NB to intersect at point B, B has to lie in plane M. We will, therefore, start by sketching a plane M and point B in the plane.

We can now place point N somewhere not in plane M, and draw the ray NB to get the desired sketch.
