Explanation: Just because a triangle has two sides and one angle congruent to the two sides and angle of another triangle does not guarantee these two triangles’ congruence. For the two triangles to be congruent, the two sides that are congruent must contain the congruent angle as well. In Step 3, Sal declares the triangles BEA and CED congruent by AAS, or Angle-Angle-Side. This is because we have two sets of congruent angles (that we proved in the first two steps of the proof) and one set of congruent sides (marked in the diagram) that are NOT the included sides.
