Retrieved from http://udspace.udel.edu/handle/19716/16742 on [enter DATE].http://udspace.udel.edu/handle/19716/16742We describe an exploratory task intended to support students’ conceptual understandings of triangle congruence with particular emphasis on the Side-Side-Angle (SSA) case. We reveal how SSA, often dismissed, is actually a challenging an interesting case for exploration.Triangle congruenceSide-Side-Angle (SSA)Other
