Answer 1

No there is not enough information. it is completely unclear if S is one or two points.

two lines define one point, three lines can define more than 1 point.

Answer 2

are you **really** having trouble with that question?

The common side is reflexively congruent to itself, so you have triangles congruent by SAS.

{note to non-geometry teachers: there is only one point at S , those diagrams would not make the two distinct points off by half a millimeter if that was the scenario they were trying to paint}
