Geometry

Question Analysis:
This question involves proof by contradiction.
The main focus is on setting up the correct initial assumption to disprove the negation of the conclusion.

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:
p: “Triangle has two equal angles”
q: “Triangle has two equal sides”
So we assume:
→ Triangle has two equal angles (p is true)
→ But does not have two equal sides (q is false)
→ This leads to contradiction with triangle properties
