Welcome to Triangle and
Squares! The following visual
illustrations show the result of exploring triangle and
squares with dynamic geometry software. Site created and
maintained by Antonio Gutierrez.

Some of the results under
Triangles and Squares are special cases of
Van Aubel's theorem which
relates to squares on the sides of a quadrilateral. When
two vertices of the quadrilateral coincide some of the
special cases here are obtained. For generalizations of
Van Aubel's theorem (and associated generalizations for
triangles when two vertices coincide) go to:
