Hint: The equation for a line in 2D is y = mx + b and two lines are perpendicular if m1*m2 = -1.
Now you need to just get the equations for two perpendicular lines using your constraints and solve for the m's and b's.
Hello genii,
I bet this will stump you,
Given 5 outer points (x,y) of a five sided star:
-23.0000 17.3200 -11.3676 24.2994 -33.3421 26.0574 -11.6912 16.0979 -17.4368 26.5549
and 5 inner points of the pentagon within it:
-18.4540 24.8663 -19.2453 19.5728 -16.4195 24.7036 -21.1226 20.4364 -15.0000 22.1200
I want to determine the outer point that is opposite the pentagon corner angle that is closest to 90 degrees. In other words, I want the outer point of the triangle that makes the pentagon resemble a diamond.
How do I do that using formulae?
