Question

1) Consider two lines, r and r' that are parallel transports of each other along a third line l.

a)Consider now the three lines and look for symmetries of the figure. state a symmetry of this figure, clarifying whether the symmetry holds true for both the plane and the sphere figure or for only one of them (which).

b) If two geodesics r and r' are parallel transports along another geodesic l, then they are also parallel transports along any geodesic passing through the midpoint of the segment of l between r and r'.

Explanation / Answer

a) Yes, Symmetry will hold for both the plane and sphere as in both figure the parallel lines r and r' intersect by transversal line l making same adjacent angle.

b) Yes, True. If two geodesics r and r' are parallel transports along another geodesic l, then they are also parallel transports along any geodesic passing through the midpoint of the segment of l between r and r'.

Ask you have any doubt. Thank you
