Question

which side in the figure on the right corresponds to segment zx? jk
what is the scale factor? 2

Explanation:

1. For corresponding sides: Match the vertices of the similar polygons. The larger polygon has vertices Y, W, X, Z and the smaller has J, L, I, K. Vertex Z corresponds to K, and vertex X corresponds to I, so segment ZX corresponds to KI.
2. For scale factor: The scale factor from the smaller to larger polygon is given as 2, which means the larger figure is 2 times the size of the smaller one, confirmed by the relative side lengths of similar polygons.

Answer:

1. The side corresponding to segment $ZX$ is $KI$.
2. The scale factor is $2$.
