Properties and Calculations of Squares

The video tutorial explains how to apply special right triangles to solve a word problem involving a square. It begins by calculating the side length of a square with a perimeter of 48 meters. Then, it demonstrates how to find the diagonal of the square using the properties of a 45-45-90 triangle, where the diagonal is the hypotenuse. The tutorial concludes by showing that the diagonal length is 12 root 2 meters.
