What a good mind map example looks like

Learning how to mind map examples is easier when you can see a finished one first. A strong map starts with one central idea, splits it into a few main branches, and keeps each sub-point short enough to scan in seconds.

Put one central idea in the middle of the map.
Use four to six main branches so the map stays readable.
Keep each sub-point to a single fact, term, or step.
Add a worked example under a branch when a rule needs practice.

Example Pythagorean theorem mind map branches

Right triangleExactly one 90-degree angle · The hypotenuse is the longest side · The two legs form the right angle

The formulaa² + b² = c² · c is the hypotenuse · a and b are the legs

Finding a missing legRearrange to a² = c² − b² · Subtract before taking the square root · Check the result is shorter than c

Common whole-number triples3-4-5 · 5-12-13 · Multiply any triple by a scale factor to get another

Real-world usesChecking a square corner on a job site · Finding a diagonal distance · Estimating a screen size from its width and height
