Geometry

Question Analysis:
This question applies SSS congruence to a real-world engineering scenario, testing understanding of side correspondence regardless of order.

Key Concept Explanation:
SSS congruence requires all three corresponding sides to be equal in length.
The order in which sides are listed does not affect congruence.
Right triangle identification (6-8-10) is irrelevant for SSS determination.

Step-by-Step Solution:
List sides for both beams:
Beam 1: 6, 8, 10
Beam 2: 8, 6, 10
Compare corresponding sides:
6 = 6 (shortest sides)
8 = 8 (middle lengths)
10 = 10 (longest sides)
Confirm all three pairs match...
