Thank you for replying friend, but this is not about circle has constraint or not.
In both cases the Constraints menu does not appear.
you are probably referencing old material. The sketch constraints are now located in the toolbar, and only when you are in sketch mode. They are no longer in the sketch palette

Not up here?
Thank you so much.
I thought that when I click on the circle, constraint assigned to it will appear under SKETCH PALETTE.
I can see constraint icon on the circle but I want that, When I click on circle I will see list similar to the one below.
- CIRCLE12 TANGENT TO LINE5
- CIRCLE12 FIEXED
In my opinion this is important in complex sketch.
