Using webpage hyperlinks in presentation mode

I am currently working on a marketing presentation. One of the slides contains a description of our team, with pictures as well as hyperlinks to our facebook,twitter and google pages. I've added the hyperlinks to the symbols of facebook,twitter and google beneath every picture of a person of our team. But I can not find any way to use these hyperlinks within presentation mode. It is a assignment for class and we need to submit it to our teacher, who's probably viewing it another way than keynote (pdf or html). So I also need to make sure that the hyperlinks are working and able to be clicked on in these platforms as well.
