Problem

On a horizontal number line with origin O(0)O(0), a student first locates the point PP representing 2\sqrt2. (i) Starting from PP, describe the steps needed to construct a new point QQ on the number line such that OQ=3OQ=\sqrt3. (ii) Prove, using appropriate right triangles, that the distance OQOQ obtained by your construction in part (i) is indeed 3\sqrt3 units. (iii) Calculate the exact distance PQPQ between the two constructed points and verify your result numerically, taking 2≈1.414\sqrt2\approx1.414 and 3≈1.732\sqrt3\approx1.732.
