You have selected to use Wedge-Dash Notation for determining the stereochemical relationships between molecules drawn in different acyclic three-dimensional representations. Using this method requires four steps:

For example, compare the molecules below.

Do these molecules have the same molecular formula and connectivity?

The above two molecules do have the same molecular formula (C

Again consider the above pair of molecules and find the stereocenter(s) on each.
