The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.

Start with a trihedron with apex O and edges OA, OB, OC. Extend the edges by a factor u gt 1 to a trihedron OA^', OB^', OC^'. Then the planes ABC', ACB' and BCA' are concurrent. The common point is shown in red.

$Geometric Construction of the Square Roots of a Complex Number http://demonstrations.wolfram.com/GeometricConstructionOfTheSquareRootsOfAComplexNumber The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. This Demonstration shows a geometric construction of the square roots w_1 and w_2 of a complex number z. The square roots lie on the angle bisector of the argument of z and on a circle through the origin of radius SqrtBox[RowBox[{?, z, ?}]], which is th...
