the center
Not sure about vertices's. The circumcentre is equidistant from a triangle's vertices (no apostrophe).
A point that two sides of a polygon have in common is called a vertex. Each regular polygon has an equal number of sides as vertices.
A vertex is the point where two (or more) lines meet. Polygons have vertices.
It is called the circumcentre.
sometimes
the point that is equidistant from all vertices of a polygon.
The centroid or centre of gravity. It will also be the point where the bisectors of the angles, and the perpendicular bisectors of the sides meet.
