Answer:
B and C describe vertical angles
Step-by-step explanation:
Point R will be the common vertex of any possible pair of vertical angles.
For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.
For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.
Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.
__
Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.
