What is Extraversion in Triangle Geometry?

In summary, Extraversion is a term coined by mathematician John Conway to describe the study of what happens to theorems in triangle geometry as two vertices are smoothly moved through each other. It involves turning triangles inside out and results in "extra versions" of different entities. The term was first used in a published paper by Conway and Alex Ryba in 2015.

I came across something called "extraversion", which in that case, was swapping 2 verticies to move the triangle created by it's trisectors outside of the original triangle. I found it in a blog post:

but I can't seem to find any other reference to it other than a different blog post by the same author. Is there any article or place I can learn more about it, and if not, is there a different word that describes it? Thanks!

Extraversion: Extraversion is John Conway’s word for the study of what happens to theorems in triangle geometry as you smoothly move two vertices A and C of a triangle ABC through each other. (See a nice animation athttp://bit.ly/1gYNA82.) This movement causes the incircle (or inscribed circle) of the original ABC to change places with the b-excircle (see http://bit.ly/1HY74zi for a definition of excircle). And for any algebraic result about the incircle or incenter, a corresponding result holds for the b-excircle or excenter as long as you change the sign of b. (The incenter and excenter are the centers of the incircle and excircle, respectively.)

“There’s a pun, of course,” Conway said of extraversion in his MathFest talk (which followed Guy’s), “since I invented the term.” Extraversion involves “extraverting” a triangle or turning it inside out, Conway explained, but it also produces “extra versions” of various entities.

This might be the first published use:

What are extraversions?

Extraversion is one of the five personality traits in the Big Five model of personality. It refers to the degree to which a person is outgoing, talkative, and seeks stimulation from their environment.

What is the difference between extraversion and introversion?

Extraversion and introversion are two opposite ends of the spectrum of the personality trait of extraversion. While extraversion is characterized by being outgoing and seeking stimulation, introversion is characterized by being more reserved and preferring to spend time alone or in smaller groups.

Can a person be both extraverted and introverted?

Yes, it is possible for a person to exhibit both extraverted and introverted traits. This is often referred to as being an ambivert, where a person falls somewhere in the middle of the extraversion-introversion spectrum.

What factors contribute to someone being extraverted?

There are a few factors that can contribute to someone being extraverted, including genetics, upbringing, and life experiences. Some studies have also found a link between extraversion and certain brain structures and neurotransmitters.

Can extraversion change over time?

While personality traits are generally considered to be stable over time, some research suggests that extraversion can change throughout a person's life. Factors such as major life events, relationships, and personal growth can contribute to changes in extraversion.
