Question Analysis:
This is a contradiction setup.
The main focus is correctly negating the conclusion while keeping the hypothesis true.

Key Concept Explanation:
To prove “If p, then q” by contradiction, assume:
p is true
q is false
Then, derive a contradiction.

Step-by-Step Solution:
Assume:
Two angles are equal (hypothesis is true)
Opposite sides are not equal (negation of conclusion)
From this, you’ll derive a contradiction using triangle theorems.

Option Analysis:
A. ❌ Contradicts hypothesis
B. ❌ No contradicti...
