Frequently Asked Questions
What three measurements define a square, besides the side length?
A square is fully described by its perimeter, area, and diagonal, all derived directly from a single side length.
What are the perimeter, area, and diagonal of a square with a 5 unit side?
A square with a 5 unit side has a perimeter of 20, an area of 25 square units, and a diagonal of about 7.07 units.
Why is the diagonal of a square the side length times the square root of 2?
The diagonal splits the square into two right triangles with equal legs, so the Pythagorean theorem gives a diagonal of the side length times the square root of 2.
