### Inductive Reasoning

Inductive reasoning is the process of observing, recognizing patterns and making conjectures about the observed patterns. Inductive reasoning is used commonly outside of the Geometry classroom; for example, if you touch a hot pan and burn yourself, you realize that touching another hot pan would produce a similar (undesired) effect.

How to define inductive reasoning, how to find numbers in a sequence.
This video will define inductive reasoning, use inductive reasoning to make conjectures, determine counterexamples.

Inductive Reasoning & Conjectures

Use inductive reasoning to identify patterns and make conjectures.
Proving Conjectures & Counterexamples

Find counterexamples to disprove conjectures.

### Deductive Reasoning

Deductive reasoning is the process of reasoning logically from given statements to make a conclusion. Deductive reasoning is the type of reasoning used when making a Geometric proof, when attorneys present a case, or any time you try and convince someone using facts and arguments.
