**Mark the figure to show the given information. Explain how you would prove \( \overline{AB} \cong \overline{DE} \).**

*From Pearson Common Core - Section 4-4*

**Notes and Practice**  
CRM 2.1 - Lesson 13

**A.**

**Given:** \( \overline{AC} \cong \overline{DC} \), \( \angle B \equiv \angle E \)

- The figure shows two intersecting lines creating two triangles: \( \triangle ABC \) and \( \triangle DEC \).
- Both lines \( AC \) and \( DC \) are marked as congruent.
- Angles \( B \) and \( E \) are marked as congruent.

**B.**

**Given:** \( \overline{AE} \) bisects \( \overline{BD} \), \( \overline{DB} \) bisects \( \overline{AE} \)

- The figure shows two intersecting lines forming an X shape where \( \triangle ABD \) and \( \triangle CDE \) are visible.
- \( \overline{AE} \) and \( \overline{DB} \) are marked as bisecting each other.

**C.**

**Given:** \( \overline{AB} \parallel \overline{DE} \), \( \overline{AC} = \overline{EC} \)

- The figure depicts two parallel lines \( \overline{AB} \) and \( \overline{DE} \), with a transversal line intersecting them and creating triangles \( \triangle ABC \) and \( \triangle DEC \).
- Line segments \( \overline{AC} \) and \( \overline{EC} \) are marked as equal.
