Hello CS 1025 students (8 TTh),

    See http://www.cs.uni.edu/~jacobson

          and link to our web page:

    Week #6 is the current week.

    Right triangles have two legs and one hypotenuse.

    The hypotenuse is the side opposite the right angle, opposite
the 90 degree angle.

    The length of the hypotenuse is related to the length of the two legs
of the right triangle.

    A very popular example of a right triangle is the 3 by 4 by 5 triangle,
with the hypotenuse having length 5, which is the square root of 25.
And 25 is of course the sum of 3 squared plus 4 squared, i.e. 9 + 16 = 25.

   We'll take it slow going through the NetLOGO trigonometry, cause it can be very
tri_ing getting your head around those TRIangles.  But turtles tell us that slow
motion is going to get us there faster and patience is good.

   Oh ya, and any right triangle that has the same size for its two legs, is a
special triangle that has one 90 degree or right triangle, of course, and has two
45 degree angles.  The legs are equal and the two angles are equal.

   If you do a cro 8 for turtles, we are dealing with 45 (FORTY FIVE) degree angles
or slices of pie.
