= '''Read more Constructing Right Angles with Cords''' =

A cord divided into proportional segments can be used to form a triangle with a right angle. The familiar 3–4–5 arrangement is one example: when the sides are measured in the ratio three, four, and five, the angle opposite the longest side is a right angle. Such cord-based constructions are practical because they require no complex instruments.

In a ritual setting, accuracy of orientation and proportion mattered. A repeatable procedure using pegs and cord made it possible to transfer geometric rules from instruction to physical construction. This is an example of mathematics embedded in material practice.

For Pravāha, this section could later include an image or animation. The collapsed state would keep the article compact, while the expanded state could display diagrams, explanations, and construction steps.
