11-73.

*DE *= *BE* = *AE* = *CE.* Is Δ*DAB* ≅ Δ*CBA*? Justify your answer using a flowchart. Homework Help ✎

Make a drawing on paper and mark the four congruent segments.

Both triangles, although they overlap each other, have right angles, and they share a side *AB*.

Review the Math Notes box in section 7.1.7.

Δ*AEB* is an isosceles triangle, which makes ∠*CAB*≅∠*DBA*.

Consider which triangle congruence condition can be met.
