(4) Plot the following two planes using tracing paper on the stereonet:

 

 

(2) Plot the line that trends N23E and dips 45 degrees.  Is this line located within either of the two planes you just plotted, and how can you tell?

 

(3) Does one of the planes below dip 30 toward the SE?  If so which one?   If not, roughly where would the great circle be?

 

(2) What is the approximate orientation of the great circle plotted below? 

 

(2) Could one of the points plotted on this diagram be the pole to the plotted great circle?  If so, which one?  If not, roughly where would the pole be?
