 Triangle facts

The sum of all the internal angles of a triangle is always 180o no matter how the triangle is constructed.

The length of any side of a triangle is shorter than the sum of the other two sides. 

A triangle can always be split into two right triangles no matter how the triangle is constructed.

Basically, there are 6 different types of triangles, 3 of them are classified according to the internal angles and the rest of them are classified according to the lengths of the sides.
