The Brainliest Answer!

then draw a line between 0 and 2( 2 unit)

then draw 3 perpendicular line from the point 2

then take 3 cm on compuss and draw a arch to the perpendicular line

joint this line

u will get a right-angled triangle

then

3²-2²=5

so the perpendicular line=√5

again take ur compass and draw it on ur number line.it will be √5

see attached file

Take a point A on the number line such that OA = 1(units)

2] Take a point B on the number line such that AB = 2(units)

3] With centre B draw a right angled triangle ABC(right angled at A) such that AB =2 and BC =1

4] With A as centre and radius AC draw an arch that cuts the number line at P

5] Then, AB = AP = √5

6] OC =OA+AP=1+√5.
