I am trying to understand the notion of quasi-geodesic in Alexandrov space with curvature bounded below following [the Perelman-Petrunin paper][1]. I have two questions:

1) Is it true that the shortest geodesic is a quasi-geodesic?
2) Given a continuous path which is a union of two shortest geodesics with a common end. Under what conditions it is a quasi-geodesic?
