Algebra.Com's Answer #97874 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! the diagonals of a rhombus are perpendicular; and, like all parallelograms, they bisect each other\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "this means that the side of the rhombus is the hypotenuse of a right triangle formed by half of each diagonal and the side\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "by Pythagoras __ s^2=(14/2)^2+(12/2)^2 __ s^2=7^2+6^2 __ s^2=49+36\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "C is looking pretty good \n" ); document.write( " |
