Pitch is defined as the distance between a point and a __________.

• A. Similar corresponding point
• B. Opposite point
• C. Adjacent point
• D. End point

Answer: (A)

Pitch describes how far apart repeating features are by measuring from a point to the same point on the next repetition. That makes the missing term "similar corresponding point" the best fit, because pitch is about the gap between identical locations on successive repeats (such as crest to crest on adjacent threads or teeth). The other options don’t capture this idea: an opposite point is a mirrored location, an adjacent point would be a nearby point on the same feature rather than the same point on the next repeating feature, and an end point isn’t a specific corresponding point.
