In the Part-Editor, use the commands in the:
|•|| : to add sketch-elements. This vertical and to the left of the graphic-area.|
|•|| : to add and edit constraints to and between sketch-elements. This is vertical and to the right of the graphic-area.|

In the Part-Editor, the is to the RIGHT of the graphic-area.
MERGE-POINTS : Deletes a Point. You cannot remove a 'Merged Point'.
|•||Use to join sketch-elements end-to-end, and remove one of the Points.|
COINCIDENT CONSTRAINT : Does not delete a Point. You can delete a Coincident-Constraint later and move the Points apart again.
|•||Use to move together two Points, or a Point to a Line, or a Point to an Arc or Circle.|
|•||Use for 'construction' geometry.|
You cannot over-constrain a sketch-element in the Part-Editor [SolidWorks will allow you, but you are given a warning].
A Point has 2 degrees-of-freedom [DOF]. It you add a 'coincident constraint' between a Point and a Line, you remove 1 DOF, and 1 DOF remains. The Point can slide along the Line.
You cannot then add a new constraint between the same Point and a Point at one end of the Line. A constraint between a Point and a Point would remove 2 DOF, but there is only 1 DOF that remains.
