The Pythagorean Theorem

The Pythagorean Theorem is probably the most well known theorem in trigonometry. It states that the sum of the squares of the sides of a right angle triangle is equal to the square of the hypotenuse.

The proof of this theorem can be seen by making a square from four traingles. In the square it becomes evident that a^2 + b^2 = c^2
