Theorem of the Day

Java applet illustrating Morley's Miracle

The applet here, created using David Joyce's Geometry
Applet software, provides a test of geometric skill: click on
the bottom vertices of the small, red, equilateral triangle to move and
resize it. Clicking on vertex X moves the whole drawing. Now, challange a friend to move the vertices of triangle ABC so that the intersection points, a, b and c,
exactly fit the equilateral triangle. Space permitting, it is always possible. |
