Um, I'm going to have to disagree with Scirocco here. Right concept but I think he went the wrong way.

Frame one is classic geometry so we will compare to this frame. Same conditions of comparison as we assume the bars and seat are at the same height and here it would be nice to know the head tube length of the 3 frames because this WILL make quite a difference.

Frame 2 has the same top tube length but with a steeper seat tube angle which means its LONGER in reach than frame 1 although the steeper head tube angle is eating into the difference slightly.

Frame 3 has a shorter top tube length at the same seat tube angle which means it is 10mm shorter however it does have a quite slacker head tube angle which is making the difference shorter so its not the complete 10mm shorter. Now if you had a really tall head tube or high handlebar height it would be negating any difference in a hurry.

Comparing head tube height between the 3 frames will tell you as much as the other specs.
