βˆšπŸ“ on the Number line Represent βˆšπŸ“ on Number Line Let’s draw the number line Hence, point P is βˆšπŸ“ Using Pythagoras Theorem OB2 = OA2 + AB2 OB2 = 22 + 12 OB2 = 4 + 1 OB = √5 Ex1.2,3 Locate √5 on the number line For drawing √5 we consider Pythagoras theorem. Using Pythagoras theorem Hypotenuse2 = Base2 + Height2 Hypotenuse = √("Base2 + Height2" ) Hypotenuse = √(2^2+1^2 ) Hypotenuse = √(4+1) Hypotenuse = √5 Point P is the point of √5
