   45 This problem illustrates how you can Java applets in a WeBWorK example.
   46 This Java applet and data were created using Geometer's Sketchpad.
   47 WeBWorK can use existing $BBOLD JavaScript$EBOLD  and $BBOLD Java $EBOLD code to augment its capabilities.
   48 $HR
   49 First view the figure in the
   50  \{ htmlLink( "${htmlURL}test2.html", "java applet",q!TARGET="JAVA_APPLET"!)\}
   51 . (This may take a minute to load.)$BR
   52 The java applet figure illustrates a triangle and its median.
   53 You can drag the corners of the triangle to change its shape.
   54 $HR
   55 Calculate the
   56 ratio of the areas of the two colored triangles.
   57 $PAR
   58 The ratio of the areas = \{ans_rule(5)\}
   59 $PAR
   60 Will this ratio be different for different triangles?$BR
   61 \{ ans_rule(5)\}
   62 $PAR
   63 We are working on allowing
   64  java applets to be included directly in WeBWorK problems
   65 without using an external link. This merely requires that we
   66 be able to specify the directory in which the java applet resides;
   67 for security reasons, it can't reside in the same directory as the
   68 problem.
   69 $PAR
   70 You can view the \{ htmlLink(alias("prob6.html"),"source", q!TARGET="source"!)\} for this problem.
   71 or consult the \{ htmlLink("/webwork_system_html/docs/techdescription/pglanguage/index.html","documentation") \}  for  more details on the PG language.
