To solve the problem, we need to identify the three pairs of equal parts in triangles ABC and DAB, and then determine which of the given statements about the congruence of these triangles is meaningful. ### Step-by-Step Solution: 1. **Identify the Right Angles**: - Given that DA is perpendicular to AB and CB is perpendicular to AB, we can conclude that: - Angle A (in triangle ABC) = 90° - Angle B (in triangle DAB) = 90° ...
