Geometry

Question Analysis:
Tests ability to recognize proper ASA configuration.

Key Concept Explanation:
ASA requires:
Two pairs of equal angles
The side between those angles equal
Here AB is clearly between ∠A and ∠B

Step-by-Step Solution:
∠A = ∠D (first angle pair)
AB = DE (included side)
∠B = ∠E (second angle pair)
Perfectly matches ASA conditions

Common Mistakes:
Confusing the order of el...
