Which combination of figures are similar and why?

(1 point)
• Figure 2 and Figure 3; the figures are both vertical.
• Figure 1 and Figure 3; one figure is larger than the other.
• Figure 1, Figure 2, and Figure 3; all figures are rectangles.
• Figure 1 and Figure 2; the side lengths are proportional and corresponding angles are equal.

The correct combination of figures that are similar is Figure 1 and Figure 2. This is because the side lengths of the two figures are proportional and the corresponding angles are equal.
