Show how root 5 can be represent on number line

1.	Show how root 5 can be represent on number line
Answer» According to the Pythagoras theorem, we can conclude that {tex}{\\left( {\\sqrt 5 } \\right)^2} = {\\left( 2 \\right)^2} + {\\left( 1 \\right)^2}{/tex} We need to draw a line segment AB of 1 unit on the number line. Then draw a straight line segment BC of 2 units. Then join the points C and A, to form a line segment BC. Then draw the arc ACD, to get the number {tex}\\sqrt 5 {/tex} on the number line.
