Hi! I need to intersect two lines in differents Sketchs and planes with a tangent mode

Not sure what you are trying to achieve. You can add the fillet radii after you creat (extrude) a body. Looks like you are adding the radii in the sketches prior to extruding, hence the need for tangency.  
Hope this helps.

To achieve what you are asking, here is a way. Create a dummy body just for the purpose of making a plan perpendicular and adjacent to the front corner. after sketching lines and making the circle tangent, remove the dummy body.

Thanks @TigerMike…

I was trying to sketch the lines to apply sweep

You can use the edges of the body, for the sweep tool, after the sweep hide the dummy body
