6 panels showing the construction of the intentre of a triangle using circular arcs each centred at the intersection of the perpendicular bisector and the opposing angle bisector.

Today I was messing around on #goegebra just doing some #recreationalmaths, and I found an invariance that was new to me.
The 'centre' of a triangle can be defined in thousands of different ways, but often the definition has multiple constructions.
Enjoy my construction of the #Incentre
