Why is a (90^\circ) angle necessary in a square root spiral?

Answer and explanation

Correct answer: ताकि पाइथागोरस प्रमेय का प्रयोग किया जा सके

A square root spiral is formed using successive right-angled triangles. The (90^\circ) angle allows the use of Pythagoras’ theorem to find each new hypotenuse, producing lengths such as \(\sqrt{2}, \sqrt{3}, \sqrt{4}\), and so on. Equilateral triangles cannot produce this construction. Exam tip: If successive hypotenuses represent square roots, look for a right triangle and Pythagoras’ theorem.
