which side in the figure on the right corresponds to segment yx?
what is the scale factor?

Explanation:

Step1: Identify corresponding sides

In similar figures, corresponding sides are in proportion. By observing the shape and orientation of the figures, segment \( YX \) in the left figure corresponds to segment \( HJ \) in the right figure.

Step2: Calculate scale factor

Count the length of \( YX \) and \( HJ \) using the grid. Suppose \( YX = 2 \) units (counted on the grid) and \( HJ=4 \) units (counted on the grid). The scale factor \( k=\frac{\text{length of side in larger figure}}{\text{length of corresponding side in smaller figure}}=\frac{HJ}{YX}\).

Answer:

Corresponding side: \( HJ \); Scale factor: \( 2 \)
