How to apply the Pythagorean theorem in real life?

The Pythagorean theorem can be applied in real life to determine the shortest distance between two points, such as when measuring the diagonal distance across a rectangular space, like a room or a yard. It is also useful in construction, where ensuring that walls are square requires checking that the lengths of the sides of a right triangle formed by the walls adhere to the theorem. Additionally, it can be applied in navigation or mapping to calculate straight-line distances between locations.
