the shadow represented by figure defg changes to form figure defg. how do the figures compare? the figures are the same? but not the same? size shape

Explanation:

Step1: Analyze the shape

By observing the figures \(DEFG\) and \(D'E'F'G'\), we can see that the angles between the sides of the two - figure are the same. For example, if \(DEFG\) is a rectangle (assuming based on the right - angle - like appearance in the grid), \(D'E'F'G'\) also has four right angles. So, the shape is the same.

Step2: Analyze the size

Count the number of unit lengths on the sides. Suppose in the grid, if the length of \(DE\) (in \(DEFG\)) is \(2\) units and the length of \(D'E'\) (in \(D'E'F'G'\)) is \(4\) units (by counting the grid squares along the side), and the width (if it is a rectangle - like figure) also has a similar scaling. So, the size is different.

Answer:

The figures are the same shape but not the same size.
