Problem

Given two fixed, distinct points $B$ and $C$ on plane $\mathcal{P}$, find the locus of all points $A$ belonging to $\mathcal{P}$ such that the quadrilateral formed by point $A$, the midpoint of $AB$, the centroid of $\triangle ABC$, and the midpoint of $AC$ (in that order) can be inscribed in a circle.

Solution

Coordinate bash with the origin as the midpoint of BC using Power of a Point.
