📐 Powered by Geometry:
This app runs on the Pythagorean Theorem, the gold standard for diagonal and side calculations:

a² + b² = c²

Side A = √(c² - b²)

Side B = √(c² - a²)

Side C (Diagonal) = √(a² + b²)

It’s more than just a diagonal calculator app – it’s your on-the-go assistant for any angle, side, or layout problem!
