Sum of all the internal angles of a triangle is always 180 degree no matter how the triangle is constructed.

Is a triangle, which one angle is a right angle that is a 90 degree angle. The side opposite to the right angle is called the hypotenuse. The adjacent to the right angle are called legs.

Pythagorean Theoremthe sum of the squares of the lenghts of the legs equal the sqaure of the length of the hypotenuse.
