Geometry

Question Analysis:
This question involves conditional statements in geometry and the application of the Law of Detachment to determine a valid conclusion.
The main focus is on correctly identifying the direct application of the given conditional statement.

Key Concept Explanation:
The Law of Detachment states that if a conditional statement "If p, then q" is true and the hypothesis (p) is known to be true, then the conclusion (q) must also be true.

Step-by-Step Solution:
Identify the given conditional statement:
"If a figure is a square (p), then it has four equal sides (q)."
Apply the Law of Detachment:
If we know a figure is a square, we can conclude it has four equal sides (directly following the conditional statement).
Look for the correct answer choice:
Only option C correctly follows this reasoning.

Option Analysis:
A: Incorrect, as having four equal sides does not necessarily mean a figure is a square (it could be a rhomb...
