A wedge means it is coming towards you (picture straight out of the paper). And the dash means that it is going directly away from you (straight behind the paper). The wedge and the dash are in the same plane, just in opposite directions. Its a 2d representation of where the atoms or molecules are in 3d space.

The dark wedge means it's coming towards you through the paper/screen and the dashed wedge means it's going away from you through the paper/screen. It is used to denote the three dimensionality of certain molecular shapes. Hope this helps!
As others have said above, wedges and dashes are used to help you visualize the shape and structure of the molecule. If you had a 3-d model of the molecule in front of you, a wedge indicates that the bond is facing towards you while a dash indicates that the bond is facing away from you.
Hi! The wedge indicates the bond coming towards you while the dashed line represents the bond extending further away from your perspective. They’re both supposed to help us visualize the orientation of the bonds in three dimensional space
the solid wedge means that when you are standing straight in front of a molecule that atom or lone pair is coming straight at you. A dashed line means while in the same position that atom or lone pair is shooting straight behind you.
