One line is perpendicular to another when the two angles it makes with that other
line are equal : thus , the line CD ( fig . 297. ) is perpendicular to the line AB , if
the angles CDA , CDB contain an equal number of degrees . 19. Two lines are ...

From the point C describe an arc of a circle which shall cut the line AB in two
points F and G. Then bisect the line FG , and to D , the point of division , draw the
line CD : this line is perpendicular to the line AB . Draw the lines CF , CG .
