Triangles are fundamental shapes in geometry, and understanding their congruence is essential for solving many geometric problems. This quiz will challenge your grasp of the criteria that determine when two triangles are congruent, including Side-Side-Side (SSS), Side-Angle-Side (SAS), and Angle-Side-Angle (ASA). Sharpen your skills and see how well you know these important concepts!
