I suggest you take a look at the Wikipedia article on "triangle", or at some similar source. I am sure you can find lots of interesting facts there.

I can get you started with one: Nobody who knows anything about it calls it "the pi of a circle". Pi is pi.
To explain earthquakes in any reasonable way you must use facts. Relevant personal anecdotal additions may be added for variety but must also be based on fact.
Related facts are facts that are connected or have a relationship to each other in some way. They may complement each other, build upon each other, or offer additional context or information on a particular topic. Identifying related facts can help provide a more comprehensive understanding of a subject.
