YES. Because 13+7>19.
\n" ); document.write( "If you connect two sticks of length 13 cm and 7 cm
\n" ); document.write( "(blue and red in the figure) at one end with a hinge,
\n" ); document.write( "the free ends could be at a distance of up to 20 cm (13 cm + 7 cm).
\n" ); document.write( "You get the 20 cm distance when the ends of the sticks are aligned.
\n" ); document.write( "If the sticks are at any angle other than 180 degrees, the ends of the sticks would be 3 points not aligned and would form a triangle.
\n" ); document.write( "The distance between the free ends of the sticks, measured along a straight line (black), is shorter that the distance from one free end, going throung the hinge, to the other free end (blue+red).
\n" ); document.write( "In geometry, that means that the length of a side of a triangle is less than the sum of the lengths of the other two sides.
\n" ); document.write( "At a struck stop, it is stated as \"a straight line is the shortest distance between two points.\"
\n" ); document.write( "
