ab: Summary: In this article we discuss problems of constructability in the
domain of Euclidean geometry, that is problems that ask whether it is
possible or not to construct a figure with specific geometrical
properties using a straightedge and a compass. Two examples are given:
one of constructability and one of non-constructability. These are used
to discuss contributions that a dynamic geometry environment can give
to solving such problems, in particular when proof by contradiction is
involved.
