Geometry

Question Analysis:
This question involves identifying an example of inductive reasoning, as opposed to deductive reasoning.
The main focus is on recognizing the structure of inductive reasoning, which starts with specific observations and makes a generalization that is probable but not certain.

Key Concept Explanation:
Inductive Reasoning: Starts with specific observations and makes a generalization that is probable but not certain.
Deductive Reasoning: Starts with a general rule (premise) and applies it to a specific case to reach a logically certain conclusion.

Step-by-Step Solution:
Analyze each option to determine if it represents inductive or deductive reasoning:

A) This is deductive reasoning because:
Premise 1: All right angles measure 90°. (General rule)
Premise 2: Angle A is a right angle. (Specific case)
Conclusion: Therefore, Angle A measures 90°. (Logically certain)

B) This is inductive reasoning because it starts with specific observations (every time she tests a metal, it expands when heated) and generalizes to a conclusion (all metals expand when heated).
This is not logically certain because it is based on limited observations.

C) This is deductive reasoning because:
Premise 1: If a shape is a rectangle, then it has fou...
