geometry controls

[Kfarr]

I am brand new to AD. In the attached image I am trying to exclude the portions of the horizontal lines that fall outside of the black inverted teardrop object so they will only be seen on the black object. I have tried all modes in the geometry pane with no luck. This should be simple,  however, I can't seem to get it to work. Any help much appreciated.

see attached image

thanks

Select the white lines, "Ctrl/Cmd + X". Then select the tear drop, "Layer", "Insert", choose "Inside", "Ctrl/Cmd + V".
or
Select the lines, in the layer panel, nest them in the layer of the teardrop so as to obtain a horizontal blue rectangle on the right of the thumbnail.
