Abstract: When measuring asymmetry of convex sets $ \mathcal{L}\subset\br^n$ in terms of inscribed simplices, the interior of $ \mathcal{L}$ naturally splits into regular and singular sets. Based on examples, it may be conjectured that the singular set is empty iff $ \mathcal{L}$ is a simplex. In this paper we prove this conjecture with the additional assumption that $ \mathcal{L}$ has at least $ n$ isolated extreme points on its boundary.
