The distance I display is just the x and y coordinate from the origin... real distance wouldn't be negative, should have applied an absolute value to the number before I displayed it. Thanks for pointing that out! I'll leave that in the display just to help show which line is which. Maybe it should read x and y coordinates rather than distance a and b..

Just one comment. In your Flash file, the distances "a" and "b" are shown as negatives for half of the plane (when the cursor is above the top vertex of the triangle and to the left of the line marked with "a".) Distance is always a positive number (it is a scalar quantity). This is not the same as the negative x- and y- values shown in my <a href="http://www.intmath.com/Trigonometric-functions/5_Signs-of-trigonometric-functions.php#ASTC" rel="nofollow">trigonometry ratios</a> interactive. Thanks for the tutorial.
