Plotting Irrational Numbers on a Number Line as a Spiral
While plotting an irrational number we will be using Pythagoras theorem. It state the relationship between the sides of the right angled triangle. Let us have a look at the. is a right triangle, right angled at B, so that AC is the hypotenuse and AB and BC are the sides of the right triangle,
Then,
i.e.,
If AB = BC = 1 unit then
Using this relation we can plot on the number line
Plotting any Irrational Numbers On a Number Line as a Spiral
Draw a number line and mark a point C, representing zero, on it. Suppose point B represents 1 unit as shown in fig. Then,BC = 1. Now, draw a right triangle ABC such that BC = AB = 1.
