The correct response is: Figure 1 and Figure 2; the side lengths are proportional and corresponding angles are equal.
When determining similarity in figures, we look for properties such as proportionality of side lengths and equality of corresponding angles. If Figure 1 and Figure 2 meet these criteria, then they are similar figures regardless of their size. The other options relate to orientations or the general shape of the figures but do not provide the necessary conditions for similarity.
