Consider the Reflexive Property of Congruence.
Congruent? Yes.
x=2
Flowchart: See solution.
Examining the diagram, we notice that the triangles have a pair of congruent sides and a pair of congruent angles. Additionally, the two triangles share a side. According to the Reflexive Property of Congruence, this side must be congruent as well. Let's add this to the diagram and label the vertices.
