Why do you think the Combination Square is better to use than the tape

measure for making precise measurements?

The correct answer to the following question will be "Because the head acts as a stop".

Explanation:

Since the head serves as either a stopping (especially in comparison to something like a floppy tape clip or hanger), the combination square seems to be more reliable and accurate than those of the tape measure. And maybe you'll know that certain style outlines are still square to something like the sides or finishes.

So that the above seems to be the right answer.
