Suppose angle PQR and RQS are adjacent angles. Whats side do these angles have in common?

I agree.

Okay! Thank you :)

To determine which side the adjacent angles PQR and RQS have in common, we need to understand the concept of adjacent angles. Adjacent angles are two angles that share a common vertex and a common side but do not overlap. In this case, the common side of the adjacent angles PQR and RQS is QR, so the correct answer is C: QR.

To solve this type of problem on your own, you need to visualize the given angles and look for the side that connects the two angles. Pay attention to the wording and the relationships between the angles to accurately identify the common side they share.
