No More Lines on Rectangles

Hey there, I'm used to my rectangles having lines that I'm able to use to align everyting perfectly, but i must have clicked something and now my rectangles no longer have their "lines". They still have their strokes, but the "lines" aren't there. Here's a pic: 

I'm assuming I clicked a setting, but I can't find anything here or on Google that tells me how to set it back. Thank you!
