This unit deals with
some formulae connected to Thales' theorem. Rather than giving
rigorous, stepbystep demonstrations, this unit offers the advantage
of verifying conclusions and properties in a straightforward manner.
To conclude, different examples of similarity in triangles and
polygons in general is also focused on, through an interactive
approach.
There is an
introduction to metric relations in a rightangled triangle: the
theorem of the sides adjacent to the right angle and the perpendicular
height theorem.
