Answer:
To represent √5 on a number line let's consider an integer 5.
We can express 5 as the sum of squares of two numbers.
So, we have 5=2²+1²
The above equation follows the pythogoras theorem with √5 as the hypotenuse,2 and 1 as the other two sides of the right triangle respectively.
This shows that we need to construct a right triangle with sides 2 and 1 units so that the hypotenuse become √5 units on the number line.
