βπ on the Number line Represent βπ on Number Line Letβs draw the number line Hence, point P is βπ Using Pythagoras Theorem OB2 = OA2 + AB2 OB2 = 22 + 12 OB2 = 4 + 1 OB = β5 Ex1.2,3 Locate β5 on the number line For drawing β5 we consider Pythagoras theorem. Using Pythagoras theorem Hypotenuse2 = Base2 + Height2 Hypotenuse = β("Base2 + Height2" ) Hypotenuse = β(2^2+1^2 ) Hypotenuse = β(4+1) Hypotenuse = β5 Point P is the point of β5
