To show that two triangles are congruent by the SAS (side-angle-side) criteria, we need the following information:
1. The lengths of two sides of one triangle must be equal to the lengths of two sides of the other triangle.
2. The included angle (the angle formed by the two sides) in one triangle must be equal to the included angle in the other triangle.
What additional information is needed to show the two triangles are congruent by the SAS criteria?
