While constructing a square root spiral, Riya draws each new 1-unit segment parallel to the previous hypotenuse. How should the new segment be drawn to correct her mistake?

Answer and explanation

Correct answer: Perpendicular to the previous hypotenuse

In a square root spiral, each new 1-unit segment is drawn perpendicular to the previous hypotenuse to form a right triangle. Then the new hypotenuse satisfies h² = n + 1. A parallel segment does not form the required right triangle. Exam tip: check for a 90° angle at every step.
