Pythagoras Theorem says that in a right triangle, the sum of the squares of the two right-angle sides will always be the same as the square of the hypotenuse It states that "The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides". It is widely applied in solving problems in two, three-dimensional figures and trigonometry and in construction industry. The theorem is of fundamental importance in Euclidean Geometry where it serves as a basis for the definition of distance between two points. In this study, we give a brief historical overview of the famous Pythagoras' theorem and Pythagoras. We review a few selected proofs of the Theorem and discuss its applications in the construction industry. For example in surveying, carpentry, laying out squares and architectural designs.en-USPythagoras Theorem , Applications , Construction IndustryThesis
