Properties of Triangles

It would be a shame if CAT 2007 or CAT 2008 aspirants have still not discovered that geometry is one of the most important areas to prepare in the quant section. They should also know that triangle is the most common figure they will see in the geometry section. Be it a quadrilateral or a hexagon, triangles and their properties will be present in every figure. Although the ideal way to learn these properties is to practice and derive all the theorems related to these properties themselves, the students can go through this small compendium to have a quick recap of those formula. The following properties do not cover the similarity of triangles. Of course that will take an entire article by itself.
