Question

justification 2√2 on the number line.​

Answer 1

Answer:

Watch the image attached----

For the justification of $2\sqrt{2}$ you are going to make a number line of 2 times of $\sqrt{2}$

Just do as given in the picture but start from 2 in the x-axis it means to draw a line between Point 2 & 3 in the X-axis of the number line.

Consider the distance from point 2 to 3 as 1 then the hypotenuse so formed will be $2\sqrt{2}$ then extend the line using a compass.

Hope this helps ✌️
