= '''Read more Approximation of the Square Root of Two''' =

The diagonal of a unit square has length √2. The Śulba tradition preserves a notable approximation that can be expressed numerically as 1 + 1/3 + 1/(3×4) − 1/(3×4×34). This gives a remarkably close value for practical construction.

The rule demonstrates the need for numerical accuracy in problems involving the enlargement of a square or the construction of an equivalent area. It also shows that the tradition combined geometric procedures with fractional approximation.

A collapsible presentation is especially suitable here because the main article can state the result briefly, while the expanded section can contain the arithmetic, decimal comparison, and discussion of historical interpretation.
