If triangle MNO is approximately equal to triangle SQR, which of the following is true?

A. angle O is approximately equal to angle Q
B. angle M is approximately equal to angle S
C. segment MN is approximately equal to segment SR
D. segment NO is approximately equal to segment RS

If triangle MNO is approximately equal to triangle SQR, then it means that the corresponding angles and sides are approximately equal.

So, the correct answer is:

A. angle O is approximately equal to angle Q.
