Similarity is one of the "big ideas" in geometry. Note that two things may be similar in colloquial English, but it is a much stronger statement to say that they are mathematically similar. ... In this session, you will build on your intuitive notions of what makes a "good copy" to build a more formal definition of similarity.

The triangle, geometry's pet shape :-) , has a couple of special rules dealing with similarity. They are outlined below. 1. Angle-Angle Similarity - If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Similarity geometry lies between Euclidean geometry (with group I(Rn)) and Affine geometry (group A(Rn)). ... Many of the theorems of so-called Euclidean geometry are in fact theorems of Similarity geometry. For example, the well-known theorem of Pythagoras can be proved by "similar triangle" methods...
