Join these two points with a straingt line.
Place you ruler on the square as if you are going to draw the other diagonal.
Draw the line along your ruler from the top left point of the square until you reach the line you drew in instruction 2.
Draw a line parallel to the line you drew in instruction 2 that passes through the midpoint of the right side of the square as shown in the diagram.
