We do no show constraints in the graphics-area. You must find the constraint you want to delete.

1.SHIFT + Click a Circle, Arc, or Line in the graphics-area.

If the sketch-element has a TangentCtoL or TangentCtoC constraint, it shows in the Selection-Window.

2.Right-click the TangentCtoL or a TangentCtoC constraint in the Selection-Window

3.Click Delete element in the shortcut menu
