Inductive Reasoning in Geometry

This lesson introduces inductive reasoning, a method of reasoning from specific cases to general conclusions, commonly used in science. It explains the concept of conjectures and how they can be disproven with counterexamples. The lesson includes examples of pattern recognition, such as the Fibonacci sequence, and tests conjectures using even integers and prime numbers. It concludes with a discussion on using counterexamples to disprove general statements, like all fruits growing on trees.

What is inductive reasoning primarily based on?

• General rules

• Hypothetical scenarios

• Mathematical formulas

• Specific cases

How does deductive reasoning differ from inductive reasoning?

• It uses specific cases to form general rules

• It uses general rules to form specific cases

• It is based on mathematical proofs

• It relies on hypothetical scenarios
