Question

show the number is
$\sqrt{5}$
on the number line​

Answer 1

Step-by-step explanation:

$oa \: = \sqrt{ {ob}^{2} + {ab}^{2} }$

OB = 2

AB = 1

OA = √2²+1²

OA = √4+1

OA = √5

method of drawing

draw a line from point 2 at an angle of 90°

take the length from 0 to 1 in compass and draw arc on the earlier drawn line and mark newly formed point as A.

join the newly formed point with point 0.

take the distance from 0 to A

draw an arc on number line with the taken length mark as √5
