Can a fixed finite-length straightedge and finite-size compass still construct all constructible points in the plane?

How many squares can be formed by using n points?

Examples of metric spaces with measurable midpoints

From a point and continuing reflection in $2n+1$ points then midpoint of the end point and the first point is fixed

Is a polytope that has in-spheres for faces of all dimensions already regular?

Is the intersection of two distinct sufficiently small metric spheres always empty, a point or a metric sphere of lower dimension?

An arrangement of entangled squares

Is there a 4-polytope without 3-gonal and 4-gonal faces, other than the 120-cell?
