For this kind of adjustements I prefer the Trim Two function, just at the right of the one you used.
select first the strait lines, then the circles, I get strange behaviour if I select the circles first.

Draw 2 concentric circles, then 2 strait lines crossing the circles.
Select trim two
click on the part of a line that should be kept, then click on the part of the circle that should be kept, continue with the other line and same circle.
Do the same with the other circle, voilà
