Geometry

Question Analysis:
This problem involves triangles formed within a trapezoid by its diagonals. The goal is to determine if SSS congruence applies.
The main focus is on checking whether all three sides of one triangle match the corresponding three sides of another.

Key Concept Explanation:
The SSS Congruence Postulate states that if three sides of one triangle are equal to the three sides of another triangle, then the two triangles are congruent.
In this case, we are given specific side lengths for △ABE and △CDE, and we need to compare them.

Step-by-Step Solution:
AB = CD = 6 units (Given)
BE = DE = 5 units (Given)
AE = CE = 7 units (Given)
Since all three corresponding sides of △ABE and △CDE are equal, SSS applies.

Option Analysis:
A) Correct. Since all three sides match, △ABE ≅ △CDE by SSS.
B) Incorrect. SAS requires ...
