Which combination of figures are similar and why?

Figure one, figure 2, and figure 3 all figures are rectangles
Figure one and figure 2 the side lengths are proportional and corresponding angles are equal
Figure one figure 3 figure is larger than the other
Figure 2 and figure 3 figures are both vertical

Figures one and two are similar because their side lengths are proportional and corresponding angles are equal. This means that they have the same shape, but one may be a scaled-up or scaled-down version of the other. Figure three is different in size compared to figures one and two, but figures two and three are similar in that they are both vertical rectangles.
