The following questions require some thought and reaching the answer may require you to think beyond the contents of this TLP.
-
Using a Wulff net, plot the {100} poles on a stereogram aligned so that the paper is in the x-y plane. By measuring angles along great circles, with rotation of the Wulff net if necessary, plot 320, 323, 510 and 511. Find the angle between 323 and 511.
-
Plot the pole 141 by plotting two intersecting great circles on a Wulff net.
-
Plot the pole 211 by drawing small circles around 001, 111 and 110 on a Wulff net.
