While constructing a square root spiral, Rima draws a segment of length 1 unit at the endpoint of the \(\sqrt{8}\) side, perpendicular to the \(\sqrt{8}\) side. What is the length of the new hypotenuse when the new point is joined to the starting point?

Answer and explanation

Correct answer: 3

The new right triangle has legs \(\sqrt{8}\) and 1. So its hypotenuse is \(\sqrt{(\sqrt{8})^2+1^2}=\sqrt{9}=3\). Adding \(\sqrt{8}+1\) is incorrect because a hypotenuse is not the ordinary sum of the legs. Exam tip: apply Pythagoras at every spiral step.
