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
