through 20°, Rotate the line about Cfrom its new position, in the same direction, through 15°. Whatangle does the line in its final position make with its original posi-tion ? 20. The same problem as the preceding, there being, however, fourangles, 45°, 60°, 30° and 90°. The point in the last two… … Parallel Lines. 1. Parallel lines were defined tobe such as have the same direc-tion. Thus the lines in thefigure, though differing in position,have all the same direction, andare parallel. 2. AC and DE are straightlines. Using the bevel, whatdo you observe with referenceto the magnitudes of the…
