โˆš๐Ÿ“ on the Number line Represent โˆš๐Ÿ“ on Number Line Letโ€™s draw the number line Hence, point P is โˆš๐Ÿ“ Using Pythagoras Theorem OB2 = OA2 + AB2 OB2 = 22 + 12 OB2 = 4 + 1 OB = โˆš5 Ex1.2,3 Locate โˆš5 on the number line For drawing โˆš5 we consider Pythagoras theorem. Using Pythagoras theorem Hypotenuse2 = Base2 + Height2 Hypotenuse = โˆš("Base2 + Height2" ) Hypotenuse = โˆš(2^2+1^2 ) Hypotenuse = โˆš(4+1) Hypotenuse = โˆš5 Point P is the point of โˆš5
