how root 5 can be represented in the number line.

$\small \blue {\sf{αnѕwєr :- }}$

construct a unit circle (radius = 1) centered at 2 on the number line, and a line perpendicular to the number line passing through 2. Construct the segment from 0 to one of the points where the perpendicular intersects the circle. This segment has length sqrt5. Using this segment as a radius, construct a circle with center at 0. The second circle will intersect the number line at sqrt5 (the red circle in the diagram.)
