Question

locate 3 on number line​

Answer 1

⦁First construct the BD of unit length perpendicular to OB.

ㅤ

⦁Then apply the Pythagoras theorem $\rm{OD = \sqrt{(\sqrt{2})^{2} + 1^{2} = \sqrt{3}}}$

ㅤ

⦁We can locate $\rm{\sqrt{3}}$ on number line by using a compass.

ㅤ

⦁We know that, O is the center and radius OD. Now let's draw an arc which intersects the number line at the point Q.

ㅤ

⦁Therefore, now the point Q = $\rm{\sqrt{3}}$
