Final answer:
To find the missing values for the pairs of corresponding parts, you need to add the corresponding parts from the other pairs.
Step-by-step explanation:
To complete the pairs of corresponding parts, we need to find the missing values for each pair. Let's start with the first pair RST and TXY. We are given that R + XYT, XTY and TXU. Looking at the first pair, RST, we can determine that the missing value is XYU. To find XYU, we need to add the corresponding parts from the other pairs. From the second pair TXY, we have XYT. And from the third pair TXU, we have TXU. By adding XYT and TXU, we get XYU as the missing value for the first pair RST. You can follow the same steps to find the missing values for the other pairs.
