Consider a square ABCD.Then the longest point to point measurement would be between the vertices A,C and B,D.The line joining these two points is called the Diagonal.\r
\n" ); document.write( "\n" ); document.write( "The diagonal can be found by applying Pythagoras' Theorem to the 2 sides of the square.Since all angles in a square are 90degrees,the diagonal becomes the hypotenuse and the sides of the square will become the sides of the triangle.\r
\n" ); document.write( "\n" ); document.write( "In this case D^2 = (48)^2 + (48)^2
\n" ); document.write( "D^2 = 2x(48)^2\r
\n" ); document.write( "\n" ); document.write( "D = 48 Root(2)
\n" ); document.write( "
