An illustration showing the construction used to divide an angle into two equal parts when the lines do not extend to a meeting point. “Draw the lined CD and CE parallel, and at equal distances from the lines AB and FG. With C as a center, draw the dotted arc BG; and with B and G as centers, draw the cross arcs H. Join CD, which divides the angle into the required equal parts.”
