... line. But it is not a line according to the definition: for, however thin it may be, it has some breadth. Again, if we make a dot on the paper as a mark of position, the dot is not a geometrical point, for it has some magnitude. Straight Lines. Lines are either straight or curved. Everyone knows wha ...

... transversal l with respect to the lines L1 and L2, and we have to prove that L1 ∥ L2. As before, let O be the midpoint of the segment P1P2 and let R be the 180-degree rotation around O. If the rotated image of L2 is denoted by R(L2) and the rotated image of D1 is denoted by C′, then R(L2) passes thr ...
