Photoshop :: Using The Rectangle Tool

I have an image that is the birds eye view to some homes. I want to use the rectangle tool to draw a rectangle around a home and rotate it. How would I use the rectange tool to do that?

I want the rectangle to not fill with a color, instead, the fill would be transparent, but the border would be red. Then I'd like to rotate it some?

How do I do all that? I can click on the rectangle tool in the toolbox. Then click and draw a rectangle. The box fills with a color and covers whatever is underneath it, then I go over to opacity in the layer and bring it down to 0. That then shows what's underneath it. Is that the right approach?

How do I create a red border? How do I rotate the rectangle?
