Simson's Line
Simson's Line
The feet of the perpendiculars dropped from a point onto the sides of a triangle (or their extensions) all lie on a line (called Simson's line) if and only if the point lies on the circumscribed circle of the triangle. Drag the red point; Simson's line of that point is shown in red when found. There are also locators to modify the triangle.
