The Pythagorean theorem has many applications in modern life. It can be used to calculate distances in baseball diamonds, determine ladder lengths, and compare heights and weights. Builders use it to lay floors and construct buildings by calculating missing sides of triangles. Artists also employ the theorem as a drawing tool to create mosaics and triangular shapes. The Pythagorean theorem forms the basis of trigonometry and connects algebra and geometry. It continues to be important in fields like fractal geometry, cell phone location, and the construction of 3D environments in video games.
