Sliding to the Fermat Point
Sliding to the Fermat Point
The point that minimizes the sum of the distances to the vertices of a triangle is the Fermat point. If the triangle has no angle greater than or equal to then the Fermat point is an interior point. In this case the angle at the Fermat point between any two vertices is .

How could you use this information to actually find the Fermat point? Define your triangle by moving the two points and think about the question before moving the slider.
As the slider is adjusted from to the triangle moves into a position so that the Fermat point is at the origin.
